Baner Pashan Biodiversity Reserve

 

 

The foot hills of the Western Ghats are a defining feature of Pune. Much loved by Punekars, these hills attract dedicated morning-evening walkers (some of them with their dogs), nature walk groups, couples seeking a few quiet moments. Recently, a loosely-knit community of music students, artists and their friends and parents celebrated the tekdis with an evening of art and music unplugged. 

In 2003, when these tekdis (hills) came under threat of being built over, more than 75000 citizens protested. A signature campaign, human chains at Vetal Tekdi and Alka Talkies, newspaper articles and hundreds of letters to the municipality all spoke of how much Punekars value these hills. Hearing the voice of the people, the planners who revised the Draft Development Plan for the 23 fringe villages newly merged into the municipal boundaries, provided for these tekdis to be conserved under a Biodiversity Park reservation.  Besides the tekdis, the reservation also includes rivers and streams as these ecosystems too are part of the biodiversity of Pune. The biodiversity land reservation is a generic formula that applies to hill tops and hill slopes of a certain slope grade, and to land along waterbodies. It works out to about 1646 hectares in the 23 villages merged into the PMC area.

The first formal Biodiversity Reserve in Pune is being created by the municipality on a part of the hill range between Baner and Pashan. The creation of the Baner-Pashan Reserve means that a specific area to which the reservation is applicable is being fenced off and a plan is being prepared for its conservation, use and management. The Garden Dept of the Pune Municipal Corporation (PMC) is preparing this plan. How to protect the area, where plantation should be done and where it should not be done, how citizens may use the area … the Garden Dept is discussing these questions to citizens, NGOs, academic experts and local representatives as a way of evolving the management plan.

Baner-Pashan: Variety of Life

The Baner-Pashan hills lie in the western region of Pune. The hills have a variety of micro-habitats. The slopes are mostly gentle, with occasional steeper rocky gullies marking the path of rainwater run-off. At such spots, during the monsoon you might spot a crab scurrying away as you approach.

On the Pashan side, the slopes have been planted with Gliricidia (Rat-killer trees). This fast-growing tree species nourishes the soil as it has nitrogen fixing bacteria in its roots like other leguminous plant species. Often, afforestation of degraded lands is done by first planting such leguminous species to stabilize the soil and make it more nutritive for plants. Later, the Gliricidia may be slowly removed to make space for planting local species.

A large quarry, now closed, is present at the slope overlooking the Bangalore highway. Every monsoon water pools at the base converting it into a small wetland habitat. Stilts hide among the rushes looking for insects. The rocky edges of the pool harbour ferns. The quarry wall which is several metres high is like a cliff. It provides a nesting site for birds that nest in cliffs such as owls, swallows, swifts, crag martins, etc. It is also good habitat for ground birds like grey francolin and quails and a good breeding area for snakes, geckos, lizards, frogs and as it comparatively less disturbances. The grasses and related smaller creatures like grasshoppers, mantis, beetles, bugs etc provide a prey base for higher animals.

The slopes taper off towards the top which is a plateau covered with grass. If you sit for a while, you’ll hear the busy chirping of sparrows and perhaps spot a lark or a shrike. Exciting sightings such as of grass snakes and russels vipers have been noted by regular visitors of the area as well.

Were these hills covered with forests when Shivaji was fighting his battles? Or have the dhangars who still graze cattle on these hills as they have been for hundreds of years always seen these as grasslands? More on dhangars a little later, but as far as biodiversity is concerned, we don’t really know.

According to Ashish Kothari of Kalpavriksh, we city-bred people are lucky that we can see different types of habitats in the reserve. Habitats such as rocky slopes, grass land plateaus and pools of water or wetlands are as important as tree patches to sustain biodiversity.

Dr Erach Bharucha of Bharati Vidyapeeth Institute of Environment Education and Research (BVIEER) differs. ‘Several very small patches of habitats don’t really benefit the species living in them as the patch size is too small to provide for the food and other needs of a healthy population’ he says.

For now, the management plan for the Baner-Pashan reserve aims to conserve different types of habitats across the hill range. Native tree species will be added to the Gliricidia plantation enriching the variety of tree species.

Multiple Benefit

One question that Mr Yashwant Khaire, PMC Garden Superintendent puts to some of us discussing the management plan is – What is the purpose of the Biodiversity Reserve?

Surely, it is biodiversity conservation. The Biodiversity Reserve provides several unseen ‘ecosystem benefits’. It serves as a ‘sink’ for absorption of pollutants and as a source of fresh air for the city. The vast tracts of hilly vegetated lands help to absorb rain water and recharge surface streams and groundwater aquifers in the city. So, another objective is that our city should continue to receive these benefits of natural areas.

Schools and nature educators already know the wonderful educational opportunity the hills of Pune provide. On the Pashan side is the Ramnadi and the little dam across it which forms the Pashan lake. On the Baner side, you can see the Mula and if you look carefully you can spot the confluence of the Ramnadi with the Mula. The hills are a place for us urban creatures to learn about the ways of the natural world. Thus, ‘education on biodiversity’ is one stated objective of the evolving management plan.

However, apart from the straight science, geology and geography type of content, there are other lessons the hills can teach. These hills have seen cultures evolving and branching out, from the beginning of human settlement in these parts up to the present day.

These hills are used not just for walks and exercise, but also for collection of firewood and grass. Dhangars have perhaps been grazing their cattle here for several generations. The national policy for pastoral nomads guarantees right of way for them.

Standing atop the hills, one can see different patterns of settlements … glass fronted buildings, bungalows, village-like areas, tall buildings, small shacks. For the informal settlements at the base the hills are an open toilet. One wonders at the contrast of settlements, the different types of people who live around here, and the different meanings the city’s natural areas have for them: places for relaxation, for livelihood and income, for meeting basic needs.

So there is rich material here for educators. They may dwell on different ways of life, on respecting and celebrating diversity not just in the natural world, but also in human cultures. They may introduce questions on development and human progress, on city planning and equity amongst citizens.

Local Conservation Initiatives

A group of citizens on the Baner side have formed themselves into Vasundhara or the ‘Clean Earth Movement’. Many of them have been living here for the past several years. They’ve seen Baner change from a quiet peri-urban area to a popular residential and commercial area with IT companies setting up offices, malls and high-priced gated housing societies.

Civic services and regulatory mechanisms often don’t keep pace with city growth and this is what led Dr Garudkar, Sachin Walunj and others to form the Green Earth Movement. They have tried to streamline garbage management at the base of Baner hill. They are also keeping an eye out to prevent illegal construction on the hillside. Recognizing the dhangars’ livelihood dependence on the grasslands, Dr Garudkar and his colleagues have also initiated a dialogue with them to mark out which areas could be used for grazing and which could be kept for regeneration.

Every Sunday, some sixty or so members of Green Earth volunteer their time and effort for soil and water conservation along the Baner hillside. They have dug continuous contour trenches and planted trees along these in a bid to prevent soil erosion and enhance water conservation. Their persistent hard-work is showing positive results and it has been acknowledged by the municipality as well. Especially remarkable is the number of  children of the area who participate in all the activities at the hill. 

Historical Interest

The rock cut caves at Pataleshwar are well known. They are believed to be of a later vintage (8th century AD) as compared to the Karla (2nd century BC) and Bhaja (2nd century AD) caves up in the Sahyadris. Little known are the rock cut caves in the Baner hillside. They lie just above the Baner village. D D Kosambi in his book Myth and Reality: Studies in the Formation of Indian Culture [Bombay, Popular Prakashan, 1962], mentions these while discussing the transformation of the stone age cultures in and around Pune, and following the microlith tracks along Vetal Tekdi, Fergusson College Hill, Chaturshringi and beyond:

The temple at Catursrngi dates from 1786, but some local goddess must have received earlier worship at the same place. Banere, five miles away, has the next artificial but definitely post-Buddhist cave, which houses funerary steles as well as a Yamai and a Mahadev. A Tukai resides just above, in a shrine of her own at the top of the hillock. Banere is close to Vakad, on the other side of the Mula. The terrain and season were both unsuitable for microlith hunting.

 

Besides the caves and the old Tukai temple, a newer temple now exists on the Baner hill. 

Under Pressure

The issues before the city relate to how best to compensate owners when their land is acquired for a ‘common good’ purpose. Since the reservation implies no construction is possible, the opportunity cost of ‘development right’ ceases to exist. On the other hand, the possibility of constructing up to 4% of the plot size exists in older parts of the city. Citizens’ vigilance is necessary to ensure that the plan for Biodiversity Conservation is approved across all areas. Punekars and their elected representatives have to deliberate on fair policies for compensation, and to strictly ensure that the Biodiversity Park reserves are used for the purpose they have been created.

  1. A wonderful resource – what are the major threats I wonder? How much to the people of Pune use the area – do you have any numbers? Is the management plan in place yet? How many school groups visit the area? Are there any formal recreation/education facilities there – any trails and so on?

    Threats may include vandalism, walking path related erosion (since many people walk up and down, and on one of the hills there are concrete steps, and almost a motorable mud path which people take motorcycles on ocasionally), also lack of watering/ protective irrigation after tree plantation is done esp during the summer. Some people feel that there is too much stress on tree plantation and some natural grassy patches would be good for diversity; others feel that such patches would be too small any way to sustain any grassland type of creatures.

    I don’t have numbers, but could have a few interns do a quick survey for some of the really popular hills: Vetal Tekdi and Baner Hill. I think it must be close to 50 to 60 daily for Baner hill and over a 100 for Vetal. Can check. Not sure if numbers go up or down in the rains. The hills are very pretty during the rains.

    The management plan is generic, and that is one of the discussion points with the forest Dept and the PMC – the need to evolve a micro level mgt plan. There are no formal recreation facilities yet. We’ve tried a few birding trails, and plan to have interns make a trail guide type of brochure. Recently the FD has initiated a discussion on signage.

    Schools are involved on and off. Some schools like Loyola seem to have adopted the hill behind the school campus and have done stream bunds. Others have contributed to plantation work.

    Very nice and informative. Your info on the existence of ancient caves in the Baner hills was eye opening. As was the Kosambi quote. Great beginning to this site.

    Very interesting post. Dr. Bharucha’s opinion on the limitations of several very small patches of habitat (which, I presume, means fragmented green spaces) makes very interesting reading from an ecological point of view. Could he, or anyone else here, shed light on this in quantitative terms, which could help incorporate the idea into town planning regulations and practice?

    If I may suggest a minor amendment, which is important as it may otherwise bewilder readers, the correct and full title of the Kosambi book from which you quote is Myth and Reality: Studies in the Formation of Indian Culture [Bombay, Popular Prakashan, 1962]. It is commonly referred to by its short title, Myth and Reality. Using the extended title alone can cause onfusion.

    The full, text of the book, uploaded in PDF format, can be found at http://vidyaonline.org/arvindgupta/mythandreality.pdf . The text you have cited appears at lines 5-10, page 137 (of the PDF file)

    Thank you Civicus. Have corrected citation in post and added link to arvindgupta site. Am unable to delete last 2 paras 🙂

    You have mention that for afforestation, first nitrogen fixing plants like glyricidia will be planted . Then after the ecosystem is developed the glyricidia plants will be removed. How can it be ensured? Till that time glyricidia may outgrow and dominate and later may weed. How to avoid it?
