Revival of Ecological - Cultural Landscape Tapovan | Nashik
- The Coexistence of Nature and Culture -
CONTENTS Studio Brief: With increasing urbanisation, there have been pressures on the existing natural processes. Due to this phenomenon, there are conflicts areas that are often highly stressed pockets which require an in-depth and empathetic approach. Such areas are causing ecological disruption and affecting social constructs. It is the need of the hour to propose paradigms of designed ecologies to rebuild, support, and recollect gradually fragmenting land mosaics. These devised ecosystems take time to evolve and are often the outcome of multiple interactions that are dynamic in nature, operating over multiple scales across socio-economic and physiological processes. The resilience of a city - the degree to which change is acceptable before reorganization to create a new set of structures - is highly dependent on these interactions. The studio allows for self-exploratory research which gives foundation to the proposal, as well as explores design strategies to implement the research outcomes.

PROJECT BRIEF The project aims to revitalize a neglected piece of land that holds significant ecological and cultural value. The site has a rich history of culture, mythology, and religion, and was formerly part of a forest and agricultural fields, indicating that it contains rich soil. The site is ecologically rich with two rivers flowing along it, providing a rich riparian zone with much of the extant native flora. However, the site was left barren for years and was overgrazed and underutilized, allowing alien plant species to proliferate. During the Kumbh Mela festival, a tented city was built there without taking into account the natural aspects of the land. Trees were chopped down, concrete plinths were built, and the earth was disturbed, leading to several issues such as soil erosion, river silting, and the direct dumping of garbage on land and in water. The project aims to create a harmonious coexistence between ecological and cultural values by enhancing the ecological and cultural value of the site and optimizing its usage. The design will respect and celebrate the natural environment and cultural heritage of the place, recognizing that they are not mutually exclusive but rather interdependent. The project will preserve the ecological value of the site using sustainable design practices such as using existing vegetation, topography, water bodies, and inviting the local fauna. The cultural value of the site will be enhanced by designing eco-cultural trails and exhibits and integrating the existing ghats and temples into the design. The design will celebrate the unique character of the site, promoting sustainability and meaningful experiences for visitors, creating an eco-cultural tourism site. The project will help in uplifting the neglected value of the land, and serve as a model for reviving neglected lands with significant ecological and cultural value.

The Sadhugram area, located within the Tapovan region in Nashik, holds immense cultural significance due to its rich history and religious importance. The site was carefully chosen by considering the watershed area and the surrounding land, which is situated next to two rivers, the Godavari and the Kapila. This location provides fertile soil and a rich riparian zone with a diverse range of native flora. Despite its significant cultural and ecological value, the site is currently neglected and underutilized. Therefore, efforts should be made to restore and preserve the site to fully realize its cultural and ecological potential.The site boundary is considered as there are few physical and nature barriers i.e. the river edge and constructed road 17

There is a steep gradient near the river's edge. The moderate slopes with gradients of 0% to 2% or 2% to 5% are appropriate for developing plantations, prefabricated structures, and roads. If the slope is between 5% and 10%, it is suitable for constructing roads with terrace planting. The area with a slope between 10% and 33% is largely situated along the river's edge, where the terrain is exceedingly steep and unsuitable for building. 24

Observation : WEEKDAYS During weekdays, the neighborhood seems calm and peaceful, with locals visiting for their morning exercises and walks. There is not much foot traffic to the nearby temples, and by early afternoon, only local vendors and shop owners remain.In the evenings, only a few locals and visitors arrive to visit the temples or stroll around the park and ghats.
Site Sections
WEEKENDS On weekends, a large number of people visit the location, particularly the ghats and recreational park, where children can be seen having fun. Visitors from outside the area also come to see the temples and ghats. The evenings tend to be busier, with people also coming to the woodlands in the early morning for bird watching and to see the shrine. FESTIVALS During festivals, there is a lot of movement by pilgrims and people from various age groups. The Kumbh Mela, which occurs once every 12 years, attracts sages and monks from all over the world, with millions of them attending and camping behind the temple in a designated space called 'Sadhugram.' This makes the ghats more popular with tourists than with locals and puts a lot of religious pressure on the location. During festivals, the number of people visiting the ghats increases. 30
The Ghats attract visitors who come to bathe in the Godavari river, while others come to relax on the Ghats and interact with local vendors. The Ramshrushti Udyan offers a variety of activities such as jogging, running, walking, and a designated play area for children. Visitors can also enjoy the greenery and birdwatching in the leisure area. Also people visit the temples in the vicinity.

CONCEPTUAL EXPLORATIONS 33
SWOT Analysis
Strengths Ä Ä Ä Ä Ä Ä
The site holds high cultural and religious value, especially during Kumbh Mela. It has a gentle slope that facilitates the installation of pathways, tree plantations,and other features. Existing vegetation is already present in the area. A large watershed is also located near the site. Major roads run beside the site due to its proximity to a city. This makes the site easily accessible to visitors during Kumbh Mela
Site synthesis
Existing site conditions
Weakness Ä Ä Ä Ä Ä Ä
Easy accessibility
The riparian edge built into ghats Land unoccupied since the Kumbh Mela. There is an improper management of waste as evidenced by the smell of STP water and religious trash. The river is polluted as water hyacinths grown in it. River waste from the city is flowing through it, giving forth a pungent odour.
Vehicular sound Existing trees Easy accessibility
Opportunities Ä Ä Ä Ä Ä Ä Ä Site’s utilisation and environmental management present both possibilities and problems. Despite having a significant watershed, existing vegetation, and high cultural and religious value, the site is hampered by problems like exposed ghats, inadequate visitor numbers, vacant land that encourages the growth of invasive species, and poor waste management. However, there are potential solutions that can be used to address these issues and improve the site’s environmental sustainability and cultural significance, including preserving existing vegetation, using open spaces for exhibitions and plantations, and introducing new vegetation. Creating a comprehensive strategy that balances the site’s cultural and environmental concerns, promotes sustainable practises, and enhances visitor experiences will be crucial overall. 34
River restoration Regulating the surface flow via check dams, water bunds, and bio-swales The presence of greenery may attract migratory birds. Restoration of the riparian areas Eco - cultural tourism that restores both the environment and culture Restoring life to the barren land Ramayana's mythological tale being recreated

The site has a number of issues, including the fact that the ghats are exposed to the sun and that there aren’t many people there. Additionally, after the Kumbh mela, a large area of land was left vacant, which allowed invasive species to flourish. However, there are also many trees on the site and a sizable recreational area that is currently inadequately utilised.

Ecological strategies
Ecological strategies
Riparian restoration : Restoring the vegetation along the banks of streams and rivers, stabilize the banks, reduce erosion, and provide important habitats for wildlife. This can be achieved through practices such as planting native trees and shrubs, controlling invasive species, and reducing livestock grazing.
Ecological strategies
Developing riparian edge
Bio-swales Overflow drain Native species
Bioswales: Manage stormwater runoff , improve water quality,reduce flooding, recharge ground water The plants and soil in the bioswale act as a filter, removing pollutants and contaminants from the water before it enters the groundwater or nearby water bodies. Raingardens: Absorb and filter and is effective in managing storm water runoff by capturing and filtering rainwater . They improve the quality of water,control erosion, attracts birds, butterflies, and other pollinators, to the native plants planted in garden improving the ecosystem.
Top soil Mulch
Rain garden
Check dams
Check dams: Include vegetation planting, terracing, and helps in reducing water flow velocity, check dams help to improving water quality and reducing the risk of flooding and also helps in controlling the soil erosion .The sediments are trapped behind the dams and let cleaner water to move ahead . Reintroducing native plant : Restore the balance of the ecosystem This can be done through the reintroduction of locally extinct species or the reinforcement of existing populations. Controlling the growth of invasive species keeping a track on it. Requiring less water and lower maintenance, requires less water than non-native species, stronger root system which can help in holding the soil and have less soil erosion. Ecotourism It can benefit the environment by helping local communities and governments to protect and conserve natural resources,can help educate visitors about the importance of environmental conservation and sustainable practices, it can provide opportunities for scientists and researchers to study and monitor ecosystems
Riparian restoration, bioswales, check dams, and the reintroduction of native plants are all potential solutions that can help to restore the balance of the ecosystem.
Other strategies :
Additionally, ecotourism can benefit the environment by promoting conservation and sustainable practices and providing income and employment opportunities for local communities. By implementing these solutions, it is possible to protect and conserve natural resources while also promoting economic development and environmental education.

Productive Urban Landscape
Introduction
Productive urban landscapes are simply landscapes that promote 3 simple elements: Food, Ecology, and Community. They are dynamic landscapes that integrate some elements of traditional landscaping but bring in elements of the natural world and plants that provide us with food These types of landscapes can help heal our lands and feed both our bodies and our souls. These landscapes include green roofs, community gardens, and urban farms
Benefits of Productive landscape A productive urban landscape offers numerous benefits for both the environmental and community, making them an important component of sustainable urban development.

After the Kumbh Mela, rented agricultural lands are returned to their owners. However, some parcels of land remain vacant and underutilized for years. To address this issue, these parcels of land can be transformed into a productive landscape. The land can be planned and divided into sections with proposed internal roads that have cycle tracks, bioswales, and permeable paving pathways to help recharge groundwater and prevent soil erosion. Additionally, some parcels of land can be rented out for agricultural practices, allowing researchers and students to conduct workshops and experiments. This can also help to promote sustainable farming practices and increase local food production. By utilizing these vacant parcels of land, we can not only benefit the environment by promoting sustainable land use practices, but also provide opportunities for education and economic growth in the community. 60

Conclusion
In conclusion, the proper utilization of barren land that holds significant cultural and religious value can provide an opportunity to showcase how nature and culture can coexist harmoniously while addressing environmental issues. The restoration of the riparian areas, implementation of bioswales, check dams, and reintroduction of native plants can help opportunity to showcase how nature and culture can coexist harmoniously while addressing environmental issues. The opportunities for local communities, educate visitors about the importance of environmental conservation and sustainable practices, and provide opportunities for scientists and researchers to study and monitor ecosystems. The project highlights the potential for a sustainable future with a balance of human needs with the needs of the natural world. It also emphasizes the importance of integrating cultural and ecological considerations in land use planning. Such an approach can be a possible model for similar projects, demonstrating how cultural and ecological values can be reconciled to create a sustainable future. 62

The sorry state of Ecology • In 1995 wolves were introduced in Yellowstone Nation park . • Direct - indirect ecological effects were observed . • Decrease in population of Coyotes which was up to 50% . • Grizzlies were visible coming out from their winter hibernation as they were having food in winter months because of wolf hunting’s. • Elks were observed to leave the riparian zones. • Aspens and cottonwood provides shelter to beavers which were absent from Lamar river .
Short course in Ecology : G. Evelyn Hutchinson – His work dealt mainly with species and populations ecology, and he made real advances in modeling simple ecosystems. He saw that there were both producers (autotrophs) and consumers (heterotrophs) carrying out the energy and material cycling of the biosphere. Eugene Odum – (Joined Hutchinson) “It is an orderly process of community development that is reasonably directional and therefore, predictable.” “It results from modification of the physical environment by the community.” “It culminates in a stabilized ecosystem in which maximum biomass (or high information content) and symbiotic function between organisms are maintained per unit of energy flow”. Conclusion : • Huge change in ecosystem of park • The restoration of ecosystems was expect the unexpected . • It increased direct and indirect connections by 2.4x108 by the interaction of 20 species. Ecology is genuine science .Global diversity maps have been produced to see which are the hotspots regions of unusually high diversity spots .Various types of ecologist like fisheries ecology -fish stocks and their environments , ant ecologists who study a specific species and see what changes are possible if reintroduced in the ecosystem. 76
• Ecosystem change during succession is the increase in biomass over time. • Once the biomass curve levels off, some constraint has been applied to the growth of the system. • Odum describes food chains in early successional systems as simple and linear; more mature food chains are more complex, with more cycles, including the recycling of nutrients from detrital material produced by the ecosystem • Early-stage, ecosystems often lose nutrient resources, while mature ecosystems retain much of their resources within the system • During succession, niches narrow. A “broad” niche refers to the great range of environments in which organisms can live and is typical of earlysuccession systems. 77
Climax ecosystem : • One of the most misunderstood concepts is the process of a climax ecosystem in a successional sequence. • One problem with the climax concept traces to its early investigators, who saw the climax as the final steady state of a system. The error of this concept can be seen in very mature ecosystems. • Large trees are vulnerable to wind throw for instance, and overcrowded forests are vulnerable to fire and infestation by herbivore pests. • A climax ecosystem should be looked at as a mosaic of different stages of ecosystem succession.
Examples : 1. Regress under stress Ecosystems regress under stress. The removal of larger, long-lived commercial fish associated with climax ecosystems resulted in a population boom of less valuable sand eels. Researchers linked the smaller, more quickly breeding sand eels to depleted catches of commercially important herring and mackerel. It is an example of succession being pushed backward. .

2. The tale of two creeks. Three Howard Odum graduate students studied two adjacent tidal-marsh creeks on the southern coast of Florida in the 1970s One tidal marsh had a 2,400-megawatt nuclear power plant on it, the other creek maintained its natural character . This increase in water temperature “stressed” the ecosystem in the creek. Although the plant was nuclear, the stress was heat related, and it was not temperature per se, but the move away from ambient conditions – from the ecosystem’s comfort zone – that damaged the system. Even worse, the complex food web was severely compromised: the number of cycles was cut in half; the stressed ecosystem lost much of its recycling power. It leaked nutrients and energy like crazy. It wasted away. From this example and those above, it can clearly be seen that stress sends ecosystems back to earlier stages of development. They function more simply, with less diversity. They shrink. Conclusion : Ecology is a science with a lot of data. The annual cost of gathering and analyzing environmental data on ecological systems is in the hundreds of millions of dollars. Unfortunately, most of this information is unfinished and rarely synthesized. Frequently, data are collected for a specific purpose without using an experimental design that enables answers to more comprehensive questions. Mosaic of succession in forest
78
According to the data sets described above, early successional and “stressed” ecosystems lose more nutrients and water than more developed, or “natural,” ecosystems. One can direct the restoration of disturbed systems toward a desired result by using ecological principles. The nearby ecosystems should serve as a guide. Recreate as closely as possible the ecosystemic conditions of nearby systems before allowing the perturbed system to find its own new stable states. 79
Seminar IMPACTS OF URBANIZATION ON RIPARIAN ZONE
FLORA AND FAUNA FOUND NEAR RIPARIAN EDGE • • • • • • • • • • • •
Along rivers and streams, animals and plants which are hydrophilic, or love all the water they can get. This is not true of all plants, as many plants would drown if exposed to the intense amount of water at a river’s edge. However, many plants and animals have evolved for this situation. Large trees like oaks, cottonwoods, ash trees, and willows are prime members of the riparian zone community. These trees provide shelter and rich soil, under which smaller shrubs and vegetation can grow. While the trees limit the amount of light that reaches the stream, they also insulate the stream from experiencing the heating effects of direct sunlight. This increases the biodiversity within the stream, and allows many opportunistic feeders to come to the biome. Animals like otters and musk rats love the abundance the riparian zone has to offer, as well as the protection it provides from larger predators like wolves and cougars. Other animals include frogs, lizards, and snakes, all attracted by the water and abundance of prey. Many aquatic bird species make their homes in riparian areas, including birds like ducks and dippers On the basis of their ecological strategies in riparian zones, riparian plant species can be classified into four major types a) Invaders – produce large numbers of wind and water-disseminated propagules that colonize alluvial habitats; b) Endures – resprout after breakage or burial of either the stem or roots by floods or after being c) Resisters – withstand flooding for long periods during the growing season; d)Avoiders – lack adaptations to specific disturbance types (i.e. individuals germinating in an unfavourable habitat do not survive)

Introduction to the Riparian Zone • • Urbanization can have significant effects on riparian edges, which are the transition zones between aquatic and terrestrial ecosystems. Riparian areas are particularly vulnerable to the impacts of urbanization because they are often located in low-lying areas that are easily accessible for development.
• • • • • • • •
Urbanization on riparian edges is the conversion of natural habitats into impervious surfaces, such as roads, buildings, and parking lots. This can lead to changes in hydrology, increased water runoff, and erosion, which can alter the physical and biological characteristics of riparian areas, also • lead to the introduction of non-native and invasive plant species, which can out-compete native species and reduce biodiversity in riparian areas. 80
Riparius is a Latin word meaning “of or belonging to the bank of a river”. Riparian zones are an unusually diverse mosaic of landforms, communities, and environments within the larger landscape, and they serve as a framework for understanding the organization, diversity, and dynamics of communities associated with fluvial ecosystems. Riparian land is any land that adjoins, directly influences, or is influenced by a body of water. It therefore includes: The land immediately alongside small creeks and rivers, including the riverbank itself . Gullies and dips which sometimes flow with surface water . Land adjacent to drains and channels that discharge into streams or wetlands Areas surrounding lakes . Wetlands and floodplains, which interact with the river in times of flood . Vegetation dependent on groundwater supplied by a river. Riparian zone, also known as water-level fluctuation zone, buffer zone, etc., refer to flooded land that periodically emerge from the water surface because of the seasonal fluctuation of water level in rivers, lakes, or reservoirs. It is a special part of land, serves an important role in ecology and environmental resource management, and could bring economic benefits in various ways. Initially, riparian areas were considered as a type of a wetland. The properties of riparian zones could bring great benefits. By providing agricultural, environment and attractive natural landscape, and tourism. Therefore, it is essential to continuously develop an effective and reasonable measure to utilize the land of riparian zones, which could guide us to create more benefits through utilizing it while preventing it from damages and pollution 81

Riparian zones are an interface between terrestrial and aquatic ecosystems and also play a critical role in supporting biota and therefore biodiversity. Healthy, native riparian vegetation reduces the water temperature of aquatic habitats by shading. It also produces tannin which gives the water a distinctive amber colour, which further reduces light penetration of the water column. When water temperature increases dissolved oxygen levels decrease, creating conditions which are difficult to endure for cold-blooded animals whose metabolic rates may exceed available oxygen in the rising temperatures. More sunlight in the riparian zone also increases the growth of soft leaved vigorous weeds and algae that can choke the stream channel. Because the leaf material of these plants is soft, it breaks down rapidly, depleting the water of oxygen completely. This situation is one cause of fish kills. Riparian vegetation supplies energy in the form of leaf litter and other organic debris, which affects the aquatic food webs. The relative importance of the riparian zone on the in stream ecosystems varies as you move from small, narrow upland streams where the riparian vegetation has a significant influence, to larger, wider lowland rivers, where many of the aquatic ecological processes occur independently of the immediate riparian vegetation, but instead rely heavily on inputs from upstream. It is therefore vitally important to view our streams as continuum — and recognize that upstream riparian communities play a critical role in the functioning of the entire river system.

Compared to non-riparian land, riparian land typically supports a greater diversity of plants and animals, and it occasionally supports endangered or vulnerable plant species. It serves as a habitat for animals and a passageway for them to move between vegetation patches. It is the last line of defence for the preservation of water quality and in-stream life because it is typically more fertile and productive and has better soils. Riparian vegetation is distinct and diverse in and of itself, frequently being taller, denser, and structurally more complex than the surrounding native vegetation. The extent of the riparian vegetation has a significant impact on the micro climate of this region, which is frequently more humid. Vertebrate animals and fruits from riparian areas are consumed by freshwater fish. Floodplains are crucial for breeding and food supply because they connect the land and water environments. In addition to offering spawning or feeding grounds, flooded riparian vegetation protects fish and other in-stream animals from being washed away during high flows. Increased sediment and nutrients (mostly phosphorus and nitrogen) in streams can cause habitat loss, the suffocation of stream life, murky waters, and changes to the composition of plants and animals that live there. Riparian vegetation protects streams by slowing surface runoff, using nutrients and trapping sediment and other contaminants as well as protecting the neighbouring stream, riparian vegetation also protects adjacent agricultural production. It protects pastures and crops from wind and wind borne debris and offers habitat to helpful animals, particularly pollinating insects. Animals can find shelter from the elements while grazing on understory grasses and shrubs.

Functions of Riparian Zone
B. ECOLOGICAL FUNCTIONS .
PHYSICAL FUNCTIONS .
Inputs and Herbivory • Organic matter from riparian vegetation is a source of nourishment for aquatic organisms • Riparian structure appears to be the main factor influencing litter entering streams either directly or transported laterally from the forest floor depending on the vegetative cover of the riparian zone • The proportion of direct and laterally transported litter entering streams may significantly influence in-stream community dynamics as a consequence of input quality and timing. • Living riparian vegetation is a source of nourishment for many animals, from insects to mammals, that can considerably alter system function by their feeding activities. Outbreaks of defoliating insects can alter riparian forest production and thereby alter water yield, nutrients. • Riparian Zones as Nutriment Filters
Mass Movements of Materials and Channel Morphology • Material supplied to streams comes from erosion of stream banks, a process influenced by root strength and resilience • Riparian vegetation also modifies sediment transport either by physically entrapping materials, which appears to be most important in relatively low gradient environments, or by altering channel hydraulics. Wood in Streams and Riparian Zones • In the riparian forest, on exposed alluvial substrates, and in streams, it accumulates during floods in discrete and conspicuous piles. • Woody debris piles dissipate energy, trap moving materials, and form habitat. Depending on size, position in the channel, and geometry, they can resist and redirect water currents, causing the erosive power of water to become spatially heterogeneous, thereby creating a mosaic of erosional and depositional patches in the riparian corridor. • Woody debris also results in longer water residence times Riparian Zones As Ecological Corridors • Riparian zones, as networks distributed over large areas, are key landscape components in maintaining biological connections along extended and dynamic environmental gradients • Exotic plants rapidly move both up and down riparian corridors in preference to overland routes • Certainly, adaptations of many plants allow vegetative fragments and seeds to float for various distances ,while many other riparian species are dispersed by wind or animals.
PHYSICAL BUFFERS • Sediments and sediment-bound pollutants carried in surface runoff are deposited effectively in mature riparian forests as well as in stream side grasses. Sediment trapping is facilitated by sheet flow runoff, which allows deposition of sediment particles and prevents channelized erosion of accumulated sediments. • Grassy riparian areas trap more than 50% of sediments from uplands when overland water flows are BIOLOGICAL BUFFERS • Plant uptake, an important mechanism for nutrient removal in riparian forests results in a short-term accumulation of nutrients in nonwoody biomass and a long-term accumulation in woody biomass. Riparian forests are especially important sites for biotic accumulations of nutrients because transpiration may be quite high, increasing the mass flow of nutrient solutes toward root systems, and because morphological and physiological adaptations of the many flood-tolerant species facilitate nutrient uptake under low-oxygen condition VEGETATIVE PATTERNS OF DIVERSITY Riparian forests provide insights into how plant species richness varies at regional scales with respect to natural disturbances . Riparian forests maintain biodiversity through continuous upstream movement of species from other catchments or from extension of species distributions downstream during favorable environmental period. accumulation of nutrients in non woody biomass and a long-term accumulation in woody biomass. • Riparian forests are especially important sites for biotic accumulations of nutrients because transpiration may be quite high, increasing the mass flow of nutrient solutes toward root systems, and because morphological and physiological adaptations of the many flood-tolerant species facilitate nutrient uptake under low-oxygen condition VEGETATIVE PATTERNS OF DIVERSITY • Riparian forests provide insights into how plant species richness varies at regional scales with respect to natural disturbances . • Riparian forests maintain biodiversity through continuous upstream movement of species from other catchments or from extension of species distributions downstream during favorable environmental period NATURAL DISTURBANCES • Floods create heterogeneity within the riparian zone and thereby create distinct regeneration niches that facilitate the coexistence of con generic species

Vegetation provides Riffles, LWD and aquatic and emergent vegetation help to organic matter to increase O2 levels in the the stream water.
Root systems reinforce soils, provide protective surface matting, reduce erosion.
Floodplains are commonly used in agriculture and for recreation
REFUGES FOR REGIONAL DIVERSITY • Riparian forest patches have acted as safe sites for regional flora during dry periods • Moreover, riparian trees in a savannah matrix are often younger because more mature trees are removed by wind and fire as compared to continuous forests Frequent removal of mature trees reduces the rate of competitive exclusion from the community while enhancing the potential for greater numbers of coexisting species
85
Dams and Diversions
Stream channelization and levee construction.
• •
•
• • • • •
Natural riparian ecosystems upstream of dams can be destroyed when newly created reservoirs inundate riparian habitat. Dams can also cause substantial changes in downstream riparian communities by altering the magnitude, frequency, and timing of flood events and reducing the amount of sediment and nutrients delivered from upstream. Diverting water from stream channels for agricultural, industrial, and human use reduces the volume of water flowing downstream, and can have similar effects. In a natural riparian system, periodic flooding can remove sections of riparian vegetation. This leaves portions of the floodplain available for regeneration and effectively “resets” the successional timeline. Frequent disturbance naturally favors many early-successional (pioneer) riparian species. Changing flood regimes can be especially problematic when exotic species are favored by altered conditions.
• • • • • • •
Stream channelization is the process of engineering straighter, wider, and deeper stream channels, usually for improved navigation, wetland drainage, and/or faster transport of flood waters downstream. Levees are often constructed in conjunction with channelization to protect human development and agricultural fields from flooding. Riparian vegetation can be directly removed or damaged during and after the channelization process. As water flows through a natural stream, meanders are created when faster flowing water erodes outer banks and slower flowing water deposits sediment on inner banks. Many riparian plant species depend on these areas of new sediment deposition for germination and establishment of seedlings. Channel straightening and levee construction eliminate these areas of deposition, creating unfavorable conditions for riparian vegetation recruitment. By preventing overbank flooding, levees reduce the amount of water available to riparian vegetation in the floodplain, which alters the types of vegetation that can persist in these conditions. A lack of flooding has been shown to decrease the amount of habitat heterogeneity in riparian ecosystems as wetland depressions in the floodplain no longer fill and hold water. Because habitat heterogeneity is correlated with species diversity, levees can cause reductions in the overall biodiversity of riparian ecosystems.
Livestock grazing • • •
Cattle have a propensity to aggregate around water, which can be detrimental to riparian ecosystems. While native ungulates such as deer are commonly found in riparian zones, livestock may trample or graze down native plants, creating an unnatural amount and type of disturbance that riparian species have not evolved to tolerate. Livestock grazing has been shown to reduce areal cover of native plant species, create disturbance frequencies that favor exotic annual weeds, and alter plant community composition.
Fig.8.
Land clearing • • • •
In many places around the world, vegetation within riparian zones have been completely removed as humans have cleared land for raising crops, growing timber, and developing land for commercial or residential purposes. Removing riparian vegetation increases the erodibility of stream banks, and can also speed the rate of channel migration . In addition, removal of riparian vegetation fragments the remaining riparian ecosystem, which can prevent or hinder dispersal of species between habitat patches. This can diminish riparian plant diversity, as well as decrease abundances and diversity of migratory birds or other species that depend on large, undisturbed areas of habitat. Fragmentation can also prevent gene flow between isolated riparian patches, reducing genetic diversity.
