Jim McAdam (1938 and 1946) commenced forest plantation development in Wau. By 1965, the Department of Forests developed forest plantations of indigenous and exotic species in selected areas as Bulolo Wau plantation area 1949/50, Kerevat (near Rabaul) 1951, Mt Lawes (Brown River) near Port Moresby 1955, Asaro near Goroka in 1963 and Wahgi Valley near Mt Hagen 1965. Species planted included Araucaria cunninghamii – Hoop pine, Araucaria hunsteinii – Klinkii pine, Tectonia grandis – Teak, Eucalyptus deglupta – Kamarere, Pinus sp including P caribaea and P merkusii, Eucalyptus robusta, Eucalyptus grandis, Anthocephalus cadamba – Labula, Ochroma laogpus –Balsa, Terminalia species including T. brassii.

The Department employed entomologists as Barry Gray, Ross Wylie, Brenton Charles Peters, and Senior Technical Research Officers as Neville Howcroft. Ted Gray. Source ANU AFS Archives 1951.Ted Gray2 (TPNG Forests 1946-1969) recalled that Jim McAdam (TPNG Forests 1938- 1959) collected seed and established a nursery at Wau soon after the War. Jim McAdam in his presidential address “Forestry in New Guinea” in 1952 to the Papua and New Guinea Scientific Society states 45 acres of hoop pine and klinkii pine were planted the previous year. Ted Gray could not recall any substantive research being conducted during his time at Bulolo from 1952-1954. The early plantings in the Bulolo-Wau area copied the techniques developed by the Queensland Department of Forestry. 2

A description of early research in the Brown River was made by Robin Levingston (TPNG Forests 1952-1967) Reafforestation with teak. in the South Pacific Bulletin 1967. Robin described the establishment of an eight-acre trial in 1955-56 of Araucaria, Cedars, Eucalypts, Pinus, and Teak. The teak was very successful while the others were failures or marginal and following further trials in 1958-1959 the first large plantings of teak in the hilly country commenced and a reduction in planting the logged lowland rainforest. The seed for the original Brown River plantings came from the old German teak plantings at Sek near Madang. These German plantings (dated 1914?) of some 2400 acres had the best trees harvested by the Japanese during WW2. Joe Havel with students studying botanical specimens PNG Forestry College Bulolo. Photograph 1964 Dept. of Forests Port Moresby. Joe Havel (TPNG Forests 1963-1965) was the first full- time silvicultural researcher in the Department of Forests in Papua New Guinea. Early research into Klinkii Pine silviculture4 was undertaken by Joe Havel which was completed by 1959 and published in 1965. Joe Havel in his M.Sc. Thesis (p. 146) acknowledged his time at Bulolo from 1952-1954. Havel, in the introduction in his M.Sc. Thesis (Thesis submitted to the University of Queensland 1959), notes “the investigations here described were intended to deal with the many problems met in raising and planting klinkii pine seedlings. Though the Queensland hoop pine technique were useful as a guide, a complete investigation of all aspects of raising and planting klinkii seedlings was necessary.” p.8. His pioneering studies on klinkii pine in 1955-59 enabled the species to be grown more successfully in the nursery and plantations (Ref. Plantation establishment of klinkii pine (Araucaria hunsteinii) in New Guinea. Commonwealth Forestry Review, 44(3): 172-187 and Joe Havel’s story). Joe Havel did extensive research into the ecological studies of the PNG Araucaria forests which have been published internationally. Ref. Havel, J. J. 1971.

Leon Clifford (TPNG Forests 1958-1975). In 1963 Leon Clifford was transferred from Kerevat to Bulolo where he worked on tree improvement in Araucaria. Spp. REF. Tree improvement hoop and klinkii pines. Item No. 11, Silvicultural Research Conference, Bulolo, 1968. Pp. 1-9 plus three append.); Leon also established several yield plots and conducted a survey of termite damage in the hoop pine plantations (refer Ardley, Clifford, and Gay “Termite damage to plantation-grown hoop pine in New Guinea”. Paper presented to 12th International Congress of Entomology. Pp. 680-681, 1964).

In 1965 Leon was catapulted into the position of Acting Principal of the Bulolo Forestry College following the departure of Joe Havel. The yield plots were used by the students at the forestry college for training in mensuration and growth studies. Leon left Bulolo in late 1970 to accept a position at the Regional Forestry Office, Lae (refer Leon Clifford’s story). L-R. Chris Borough, John Smith at plaque for Jim McAdam at McAdam Memorial Park Wau. Photo credit John Davidson. John Smith (TPNG Forests 1956-1976). In 1964 John Smith commenced studies on hoop pine and Pinus. John introduced Pinus spp. into the Highlands. In 1970 he published the silviculture of Pinus in Papua New Guinea. Bulletin No. 5, Division of Silviculture, Department of Forests, Port Moresby, Pp. 1-32. In Bob Thistlethwaite, Neville Howcroft, and Dick McCarthy Bulolo legume field day 1974. Photo credit John Davidson. Neville Howcroft (TPNG Forests 1965-2017) in October 1965 was recruited from the Queensland Department of Forests. Neville Howcroft’s forestry duties became more diversified over time involving, forest protection with entomology, while in other areas leading into the establishment of tree breeding programs and seed orchard of several Pinus species using clonal and seedling seed orchard strategies). Howcroft trained staff and initiated PNGs first ever controlled pollination program to produce its first hybrids involving Pinus merkusii provenances and Pinus Latteri. Shortly after this he became responsible for the Araucaria improvement and research program. This now included the establishment of PNG partnering FAO in exploration of natural forestry resources and perceived conservation status, estimates of seed production, time, and ease of access and to expedite collections for national and international provenance trials and to identify and recommend ex situ conservation stands. Initially this involved PNG and West Papua Araucaria cunninghamii and A. hunsteinii as well as with Eucalyptus deglupta; these followed targets identified and set by the new senior staff, Mr Barry Gray and Dr. John Davidson and in collaboration with Australia National Tree Seed Centre, ACIAR and overseas supporters and partners interested in specific PNG genera and species. Neville Howcroft and John Smith conducted trials on Pinus genetics and established hoop pine yield plots in the Bulolo and Wau plantations. In 1970 John was transferred to the Eastern Highlands as the Regional Forest Officer based at Mt. Hagen. Neville continued the research program on Pinus and other projects while attached to the Bulolo forestry station and in April 1972 he joined the Forest Research Station. Neville had a long and distinguished career in Papua New Guinea departing in 2017 (refer Neville Howcroft’s story). The loss of Alan Cameron, John Smith, and Leon Clifford in 1970 left an enormous void in silvicultural research in the Department of Forests. 8

John Davidson (TPNG Forests 1962-1980) addressed the void in research on kamarere. John studied kamarere at Kerevat (June 1967-March 1969 and from October 1970 to January 1971) for which he was awarded a Ph.D. in 1972 from the Australian National University (Thesis titled “Variation, association and inheritance of morphological and wood characters in a tree improvement program for Eucalyptus deglupta Blume”. In March 1972 John transferred to the forest research station as head of the silviculture section (refer John Davidson’s story). Much input for plantation development was undertaken by the regional and district forest offices in the nurseries and plantations in consultation with Kevin White. “Uncle” Ted Collis and Neville Howcroft (before joining the Forest Research Centre) recalled their work under the guidance of Kevin White and John Godlee (TPNG Forests 1952-1980). The department also conducted numerous trials of different tree species at various locations in Papua New Guinea and as the plantations matured different thinning regimes and silvicultural practices were tried.

FOREST TREE PLANTATION DEVELOPMENT Globally,5 plantation forests have increased from around 100 million to 180 million hectares in just 20 years. There is no doubt that plantation forests are becoming the primary industrial wood fibre resource of the world. By 2025, more than half of the global wood requirement will be sourced from plantation forests. The objective of the Department of Forests was for forest plantation development in PNG to augment the supplies of logs from the natural forest. This policy recognized that plantation forests were seen as complementary to natural forests, never able to replace all the values associated with the fabulous natural forests, but where appropriately developed, helping to divert some of the pressures away from them.

Dr. Bob Thistlethwaite13 described that there are many species in PNG which are of vital importance to the village community. These species may be used for any one or a combination of the following purposes. • Fruit, edible, planted and wild • Nuts, edible and planted • Edible leaves: commonly cultivated exclusively or partly to produce edible shoots or leaves. • Buildings: rot-resistant posts, aerial members • Canoes & outriggers • Weapons • Utensils • Rope • Fuelwood • Live fencing e.g., NG rosewood • Ornamental and shade • Custom decorations (Bilas) • Custom medicine • Custom poisons • Carving • Custom resins and glues • Custom boundary markers • Custom scents • Custom dyes and paints Issues facing Forest Plantation Development through Land Tenure The history of PNG forestry has been one of a series of ‘difficulties’ or ‘challenges’ through land tenure conflicts, sometimes between government and landowners, but more often between various groups of landowners. Each landowner wants his land logged earliest and planted soonest so he has income as soon as possible. As it is not possible to satisfy all landowners over a large area of land, some conflict or expressed dissatisfaction is inevitable. Where the PNG legislation for landowner participation through landowning companies in some joint venture or partnership arrangement with the land ‘developer’ is employed, there is perhaps a better prospect for harmonious relations between developer (whether government, foreign investor, or aid organization) and the landowning groups. However, even within such arrangements, conflicts can arise due, for example, to a perceived or real inequity in the division or distribution of cash payments for land rent, stumpage, or royalty, etc. There cannot be one simple set of priorities for PNG. The country is too large and too diverse for such an approach to have any validity in the eyes of the landowners. Rather, it is suggested, there should be several priorities to accommodate such biophysical and ethnic/social diversity. This is particularly important where the national policy for forestry 13

development is one of involving the people in the development process – the landowners, villages, and communities. If a species being promoted in an area is alien to that area, whether it originates elsewhere in PNG or overseas, then there will be little local sense of ‘belonging’ and hence at best an indifferent acceptance of the development. The exception may be where, through judicious extension and education, the promotion of a species captures the national imagination, both culturally and financially. REF. PNGAF Mag. # 9D4E of 5/4/22.

1962 Baur14 1962 described the status of PNG natural regeneration activites in PNG of 1960 although it was believed at that time that the majority of lowland rainforest was designated for agricultural development (FAO15 1960b). Baur reported on trials16 established at Kerevat ENB over some 800 acres where after logging, a climber cutting was carried out, undergrowth removed and unmerchantable stems up to 12 inches dbh felled.Where the upper canopy was not sufficiently opened, undesirable stems were ringbarked or poisoned to create larger gaps. The major species being Pometia tomentosa had abundant seedlings present which responded to increased light. After the canopy opening, two annual tendings were undertaken to free regrowth of desirable species. In a six year old regenerated stand there were 350 stems per acre with a BA of 51 sq ft per acre; the 160 best stems per acre had a mean dbh of 5.4 inches and the taller stems were over 60 ft high. Concern was expressed at the time re the impact of urbanisation from Rabaul and the increasing number of commercial species may affect the continuation of these trials. Reference is made to research17 commencing on regenerating some of PNG’s dipterocarp forests. Havel, J. J. (1962).

Ecology, 59: 203-214. Havel reported on two theories advanced on the mode of regeneration of Araucaria are examined in the light of ecological studies made in New Guinea. The first theory postulates that they are 'living' fossils dependent for their regeneration on natural catastrophes. According to the second theory, they are integral components of the forest whose regeneration patterns are similar to those of their angiosperm associates. The two species of Araucaria, - A. hunsteinii and A. cunninghamii, occur over a wide latitudinal and altitudinal range, chiefly as emergents over several broad-leaf forest types. Optimum development of Araucaria is normally found in forest types whose canopy is reduced in density and height as compared with that of the tropical lowland rain forest. In two of these types of Araucaria forests of New Guinea studied in detail the size class distribution of Araucaria and the angiosperms is similar. There is an adequate representation of seedlings, saplings, and young trees. Autecological studies indicate that conditions favouring seedling development are found in the forest rather than in the open. Seed dispersal is limited to within 60-80 m of the parent tree. It is therefore concluded that the Araucarias are integral components of the forest types in which they occur, and that their capacity to colonize large openings created by natural catastrophes is very limited. 1972 Davidson, J.

Distribution of Araucaria in Papua New Guinea. Research Bulletin # 1 pp 1-56 Dept of Forests PNG. Two species of Araucaria are known from Papua New Guinea, and both are of considerable biogeographical, ecological, and economic significance. A. cunninghamii is widely distributed between 500 and 1900 m alt., but is also found at ca. 90 m and up to nearly 2800 m. A. hunsteinii (A. klinkii) has a slightly narrower and more disjunctive distributional range than A. cunninghamii; it also has a narrower total altitudinal range of 520-2100 m. Where the two species occur in the same area, A. hunsteinii usually occurs at lower altitudes than A. cunninghamii and on less precipitous terrain, though mixed stands are common. Regeneration is plentiful in most stands. Gray, B. (1973d.) Observations on insect flight in a tropical forest plantation. 1.

commercial species. The stand of unmerchantable stems remaining after logging was poisoned. When the average height of the dominant regeneration is 15m, 200 stems per hectare are selected for release by poisoning competing crowns. This minimum treatment gives the selected trees dominant or co-dominant status. At Kerevat approximately 1090 hectares have received the initial treatment and over 45 ha. the follow up treatment. The desirable fast-growing species encouraged in order of preference are Terminalia spp, Pometia tomentosa, Dracontomelum mangiferum, Pterocarpus indicus, Anthocephalus cadamba, and Octomeles sumatrana. 1974 Davidson, J.(1974a).

In 1969, the Dept of Forests PNG changed from open planting of A. hunsteinii (klinkii) to enrichment planting in the logged Araucaria forests. Gray’s paper describes results of performance of Hoop and klinkii seedlings in open and in underplanting situations. Gray’s paper addressed two species of Araucaria that occur in Papua New Guinea: A. cunninghamii and A. hunsteinii. Their ranges overlap but almost invariably one species predominates in a given site, A. hunsteinii most often at lower elevations and on gentler topography. A. hunsteinii generally has the greater mature height with a maximum of 76.9 m in this study and a record figure of 88.9 m. This is the highest tree reliably recorded for the tropics. The maximum DBH is usually similar in the two species (c. 1.5 m), but the record is held by A. cunninghamii (1.73 m). The size (diameter) distribution in two large plots covering 1000 trees of each species was very similar (strongly positively skewed). Regeneration was also abundant in eight other plots 50 m square though there was very little or no regeneration directly beneath large trees within the layer of parent litter around the bole. In the study area the mature trees of A. cunninghamii are denser than those of A. hunsteinii but the reverse is true of small seedlings (<15 cm). Complicated differences are also found in growth rates of seedlings and trees. Experimental studies are badly needed. Gray, B., and Lamb K.P. (1975).

1975 - Dr Bob Thistlethwaite described work undertaken on the domestication of Terminalia brassii and trial plantings at Kerevat and Baku on the Gogol River. T. sepicana was also evaluated along with some exotic Terminalia spp but proved (at Kerevat) quite susceptible to white ant attack. T. brassii performed satisfactorily, but there was nothing at the time to recommend it over Kamarere. However, it is well to note that there are two forms of T. brassii. One form has good form and no stilt roots, while the other has a more variable form and had stilt roots with lenticels. The stilt root variety grew in swampy ground. There were small trials of Intsia bijuga, which proved very slow growing at Baku. There are several E. tereticornis provenances in PNG, and some were used in trials, along with E. brassiana. Neither proved particularly promising over other species. Anthocephalus chinensis (Labula) was grown in trial plantations at Baku on the Gogol River, quite successfully, although as would be expected with such an aggressive primary colonizer, its initial extremely high rate of growth tapered off as the plantation matured. Once established, a restriction of side light from competing vegetation, such as bananas, did not worry Labula. Acacia auriculiformis and A. mangium were evaluated in small trials in the Sepik R. area, and commercial plantings of A. mangium were established at Gogol by JANT. The extensive Pinus trials at Bulolo, in the Markham Valley, and in the eastern, western, and southern Highlands were directed to forest establishment on impoverished anthropogenic grasslands.

A wide range of Eucalypt trials were established in the Highlands for local wood supply and to meet the needs of the tea and coffee industry for firewood. Extensive village-based and landowner plantings in the Highlands with Casuarina oligodon (Yar) for maintaining soil fertility, as fuel, charcoal, and a heavy construction timber There were firewood plantation trials in the grasslands off the road to Brown River. Rosewood has a wide distribution and is widely used in PNG. It provides extremely hot firewood, house posts, live fences, a prized carving wood and a high-end value for furniture and veneer. The tree does not always have good form in the wild. It is cultivated in the Pometia tomentosa (taun) can provide a sought-after fruit and has a multiplicity of other uses. The species is sometimes planted in gardens close to villages. Like Intsia, it is thought to require land disturbance for successful establishment and can form nearly pure stands. 1976 Gray, B.

FAO/UNEP in a series of studies from 1976 reviewed TPNG endeavours re forest tree plantation development. The following extracts describes those findings re TPNG. When the Forestry Department was established in 1946, reforestation was considered as a primary objective of forest policy. This latter stipulated that all areas logged over should be reforested to sustain in perpetuity its established scale of operations. By 1970, reforestation programmes had been developed in three locations: the Wau-Bulolo area, the Brown river area (near Port Moresby) and the Keravat area on New Britain. In the Wau-Bulolo area Araucaria spp. were planted in the logged forests and adjoining grasslands and later on also as enrichment plantings in the logged-over forests. Grazing of some 2 000 heads of cattle on 4 000 ha of plantations as a cooperate venture of some tribes has been successful and reduced tending costs (8) (17). In the late sixties the Forestry Department discontinued planting of hoop pine because of its susceptibility to diseases and insects (5) (16). The supply of a local plywood factory is based on these Araucaria plantations. In 1967 the monthly coupe was 4 700 m3 of which 1 400 m3 came from plantation thinnings (Morel, in “Tropical Rain Forests of the Far East” by T.C. Whitmore). Tropical pines (P. khasya and P. merkusii) were used for reforestation. Large plantations of kamarere (Eucalyptus deglupta) and teak have been established at Kerevat and of teak (Tectona grandis) near Port Moresby. In the Central Highlands the extensive grasslands have been used for afforestation to supply the heavily populated districts where wood material in any form is scarce and costs of 21

obtaining wood from elsewhere is high. Planting programmes were developed at two major locations: in the Goroka valley at Tranvo Asara and in the Waghi Valley of the Western Highland district. In the Goroka valley Pinus caribaea is the most successful species below 1 000 m altitude and P. patula above 1 800 m. P. khasya grows well below 1 800 m but is subject to dead topping. In the Waghi valley Eucalyptus robusta and E. grandis have been used, aimed also at producing low-cost fuel for the expanding tea industry (8). Multiple use of the plantations with introduction of desirable legumes and cattle grazing have been carried out successfully (17) (21). During the 1970s, at Bulolo, Neville Howcroft carried out a lot of work on grazing under the araucaria and pine plantations, including making several new legume introductions. This work was written up in the Forest Research Note series at the time, but the most important outcome was a field day held at Bulolo held in the mid-1970s with participants from all over and attendance of the radio media.

Small village woodlots have been established throughout PNG, each in the order of 0.1-0.5 ha (21. The DOF major forest extension program by 1971, had over forty extension nurseries supplied over 300,000 to 400,000 seedlings for planting each year. It provided information and advice on tree growing for villagers wishing to establish and manage village woodlots. Forest extension nursery Goroka. Source New Horizons DOF publication 1971.

Following the clear-felling for chip production in Gogol (Madang) attempts have been made to reforest the land. But removal of the forest cover resulted in an upward movement of the water table to lie above the surface and the initially planned Eucalyptus deglupta plantations could not be established and instead Terminalia brassii was used (21). Much research has been done on plantations. At least 18 pine species from various countries (5) but also a variety of other species were tried on different altitudes and locations. Species include Tectona grandis, Terminalia brassii, Araucaria cunninghamii, Araucaria hunsteinii, Pinus patula, Pinus caribaea, Eucalyptus robusta, E. deglupta, E. grandis, E. brassii, E. tereticornis, Acacia spp. Ochroma lagopus, Casuarina spp.

Situation in PNG re wood usage in the late 1970’s. In the Highlands a complex system of horticulture was already practised as long as 2 300 years ago. The majority of the present population which was constituted through an irregular growth over a long period of time, is dispersed and engaged in shifting cultivation. This practise has affected much of the forest over the centuries. Short fallow rotations and fire have caused extensive grasslands. It is calculated that every person requires a land area of 1.8 ha for his shifting cultivation for an average fallow period of 10 years varying from 3 to 20 years. The present use of chainsaws tends to increase the fallow period through clearing of primary forest where crops have less pest infestation (24) (25). Population growth which at the moment is about 3% causes further clearing of primary forest. Mining destruction in the past has been restricted to limited areas of alluvial gold bearing sediments. But nowadays the copper mining on Bougainville island causes a massive deforestation in the mountainous areas and further impact of sludge residue is expected. Planned major roading programmes to open areas of the Sepik and Western districts will cause large destruction (3). Programmes of cash crop plantations such as oil palms, coconut palms, cacao and others occupy large areas of primary forest. Fire is a major cause of degradation, especially around the villages and towns. Fuelwood collection in the lowlands was becoming a problem. In the Highlands, fuelwood collection was causing degradation of the existing forests and even large-scale deforestation. It seems likely that the demand for timber from abroad will be steady or increase because of the reduced availability of timber from other countries of the region. The production of hardwood chips probably will increase slowly. The fast growth of this industry did not indeed materialise as the quantity of chip wood per ha turned out to be lower than expected and the international demand for this product remains at a low level (23).

The Waghi swamps were planted with E. robusta and E. grandis these species after species trials in mid-70’s. for wood supply for tea factories. The plantation programme continued till mid 80’s and a total of about 2,000 ha were planted, mostly with pure E. robusta but also with pure E. grandis and a mixture of the two species. The description of these plantations is based on Vigus, (1986). Site factors. Waghi swamp covers an area of about 5,000 ha which constitute the flood plain of Waghi River and is about 3-5 m below the general valley floor at an altitude between 1,500-1,600m. The average temperature is quite high, around of 17.1°C with daily maxima around 24°C and minima around 12.8°C. Being in the tropics, the mean temperature varies by only 2.2°C during the year. The average monthly rainfall is about 170 mm seldom with a dry spell of more than two weeks. The total annual rainfall is 2,500 mm. The soils are dominated by dark brown, open textured, poorly decomposed peat mainly derived from Phragmites. The original vegetation cover of Waghi valley is dominated by “pitpit”, Phragmitis karkar in association with Saccharum spontaneum, the former making almost pure stands of 3-6 m high. Silvicultural techniques. The high-water table and annual flooding - up to a metre for up to a week several times a year, led to the selection of two main species, E. robusta and E. grandis. Seedlings are first raised in trays then transplanted into small plastic tubes when they have two pairs of true leaves. The soil in the tubes is fertilised with urea, 60 g per 50 kg soil, and superphosphate, 360 g per 50 kg soil. The tubes are placed in standout beds until they are about 25 cm in height. They are then ready to be planted. The planting area is first cleared and drained. The vegetation, mostly Phragmites karkar is cut, allowed to dry, and then burnt. Drains 0.6 m deep by 0.6 m wide are dug 20 to 40 m apart depending on the amount of waterlogging. These drains lead into deeper ones, (1.0 m deep and 1.0 m wide) 100 m apart. The deeper drains then lead into a main drain (1.5 m deep by 2-3 m wide) spaced at 400 m apart, and the main drain lead into major drains which are strategically placed in each plantation area and are 2 m deep by 4 m wide. The drains are arranged in a herringbone fashion to facilities flow and reduce erosion. The purpose of the drains is to lower the water table prior to planting and keep the water flowing during the wet season. The trees are planted 2.5 m by 2.5 m and have to be tended every six to eight weeks during the first year, as the Phragmites karkar regrowth is very vigorous. By the end of the second year the canopy has normally closed, and the trees are well above the competing vegetation.

The growth is variable, mostly influenced by soil type and water table. In high water table area where drainage is not good, there is almost 100% mortality. A yield table prepared from 250 temporary yield plots of E. robusta stands with no boron application showed the following results (Figure 6). The MAI at age 6 varied with site class from 17.3 m3 for site class I, 11.5 m3 for site class II, and 6.7 m3 on site class III. The average stocking in these plots was 800 trees/ha from an original 1,600. Management and utilization. E. grandis grows much faster and a mixed compartment treated with boron yielded 275 m3/ha at age 8. One tree in a 14-year-old stands of E. grandis reached 50 m in height and over 85 cm in dbh. E. robusta is a good coppicer while E. grandis does not produce coppice shoots, though faster in growth rate. A coppice with standards system has been recommended to manage these plantations. With no thinnings, the trees are clear felled at age 6-10 years leaving standards at 10 x 10 m spacing (100 trees). The main use of plantation wood is for fuelwood for the tea factories in the vicinity. However, the demand was not as high as envisaged; hence harvesting of plantations was not carried out on schedule. Presently, treated poles of these species are in high demand for fencing, house construction, electric and telephone poles. The area under plantation has, however, not increased over the years due to land disputes and financial constraints.

3. Estimated future yield for selected forest types in Papua New Guinea. 4. Forest regeneration and stand development after timber stand improvement treatment in selected forests of Papua New Guinea. The work of Vigus and Cameron found that the rainforests of PNG can be regenerated after well controlled selective logging (i.e., felling all commercial trees above 50 cm dbh). To maximise benefits, it is essential that residual stems (selected on basis of species, log length, form, crown position and crown quality) are marked prior to harvesting. Timber stand improvement can be achieved cost effectively by enriching the species mix regenerating, using nursery grown stock or transplanting wildings and then carrying out some tending operations to remove vines etc. 5. Some phenological characteristics of the major commercial forest species in Papua New Guinea. Findings included that there does not appear to be any major problem with availability of seed from major species. If forest harvesting operates on a well-controlled selection system, there will be little impact on pollination vectors. A cause for concern is the lack in some areas of commercial species regeneration in both pre- and post-harvest areas. A need to raise the cutting diameter limit in particular forest areas. Controls instituted by the PNG LCOP have reduced stand damage. Individual tree fellers and plant operators need to be individually certified. The project involved remeasurement of plots established in the 1980’s. Although established in better quality forest, growth responses were markedly superior to that in untreated stands. The issue of implementing tree marking prescriptions would be determining what species to be favoured. The report found remarkable differences between post-harvest inventory figures and permanent sample plot data for the same harvesting units. In PNG, the tendency has been to assess sustainable yield as the volume that will be in excess of 50 cm dbh at the end of the presumed cutting cycle i.e., 35 years. There is a need over time to standardise data collection, standardise forest assessment techniques and data analysis across the sector. Forest typing needs to address effective productive forest areas in the assessment of likely yields, sustainable yield, and allowable cut. This report describes 25Vigus’s work of 1993 in remeasuring plots he established in 1983,1984 and 1985 in the Provinces of Oro (Kumusi TA), East and West New Britain (Kapiuru TA) and West Sepik (Vanimo TA). Plots measured 100 metres by 50 metres and all trees above 10 cm dbh were measured, and their ground location recorded. After harvesting they were assessed for logging damage. In 1993, all trees above 10 cm dbh measured and located including new recruits. In all the plots, regeneration was immediate and profuse. The species that came to dominate over time were all pioneer species as Octomeles, Anthocephalus, Macaranga, Ficus and Hibiscus.

1996 Vigus26 1996 described the first of these assisted regeneration techniques, as applied in Kimbe, West New Britain. To-date, reforestation has proceeded at a very low level in Papua New Guinea. The most recent estimate suggests a total of 62,000 ha (Kiki, 2006), over half of which is in long standing plantations managed by the National Forest Service. Without a major reforestation programme being in place at the project level, sustainability currently depends on there being sufficient trees in the stand that survive the logging operation without being damaged, that are commercial species, and are not moribund. The PNG Logging Code of Practice 1996 was introduced to ensure reduced impact of logging operations on the residual stands of the rainforest and protection of watersheds. PNG forest policy, forestry laws and regulations and operational manuals such as the PNG Logging Code of Practice and Environmental Act provide specific guidelines on the protection of catchment areas. Poorly controlled harvesting operations can be a major cause of damage to the remaining stems in the rainforest. Page 6 of the first edition (April 1966) of the PNG Logging Code of Practice delineates that all conditions imposed by the PNG logging code of practice will be in compliance with requirements of the Forestry Act 1991 as amended, Environmental Planning Act Chapter 370, Water Resources Act Chapter 205, Environment Contaminants Act Chapter 368, Conservation Area Act 1978, Investment Promotions Act No. 8 of 1992, Public Health Act Chapter 226 and its regulations (Drinking Water 1984), PNG labour Law, Industrial 1998

costs of the two principal methods of reforestation, mentioned in the title, which are proposed for replacing PNG’s Forest Resources. The presentation outlines the history of the development of the technique of Reforestation Naturally and briefly discusses the way in which the technique has been further developed for large scale application. Reforestation Naturally is a technique developed by the author where land ownership resides with people rather than governments. Reforestation naturally has two major advantages: It can increase the number of high value trees from the initial quantity of 8-10/ha to 2530/ha in 35 years’ time and it preserves the “non-economic” benefits of the forest.

2002 Howcroft 200228. The balsa manual: techniques for establishment and the management of balsa (Ochroma lagopus) plantations in Papua New Guinea. Following the eruption, recognition of the economic potential of balsa, coupled with concerns about the lack of extension services and information about the state of the industry, led provincial and national authorities to request overseas assistance. This resulted in the establishment of the East New Britain Balsa Industry Strengthening Project, under the guidance of Neville Howcroft, funded by the International Tropical Timber Organization (ITTO). The project operated from 1996 to 2003.
