TREE PLANTATION FOR LOCAL BIODIVERSITY CONSERVATION THROUGH ECOSYSTEM APPROACH
Review Report – C D Deshmukh Udyan (March 2016)
Review Report (March 2016)
In collaboration with OASIS, a tree plantation project was implemented by Tata Motors Ltd. wherein 14,000 saplings were planted for creating habitats supporting local biodiversity. 7000 saplings were planted at Maharashtra Nature Park and 7000 at CD Deshmukh Udyan. In the first year 52% mortality was reported and 1000 saplings were replanted at MNP. And 8% mortality was reported and 1800 saplings were replanted at CD Deshmukh Udyan.
This is the second year of the project and the first project report for 2016. Currently the habitat is looking dry at MNP and there has been approximately 75% of mortality with surviving plants are 1767 out of 7000 saplings planted. And 56% of mortality with surviving plants are 2836 out of 7000 saplings planted at CD Deshmukh Udyan. A total 24 species of butterflies were observed at the Maharashtra Nature Park (MNP) and 6 species at the C.D. Deshmukh Udyan. The plants like Periwinkle, Jamaican Blue Spike, Pentas were in full bloom. However the butterfly population at the C.D. Deshmukh Udyan has gone down compared to the last report. It was observed that both the sites are facing water shortage problem. As a remedy, we will develop saplings from the mature plants during the monsoon and compensate for the mortality.
This report is based on three review visits on 22 December 2015, 9 February 2016, and 5 March 2016, at MNP and 9 February 2016, 6 March 2016 at the C.D. Deshmukh Udyan.
1.1 Maharashtra Nature Park (MNP):
A review visit was conducted on 22 December 2015, 9 February 2016, and 5 March 2016, at the Maharashtra Nature Park site to check the plant growth. During the visits it was observed that the habitat was looking dry and the ground was covered with leaf litter. It was observed that there was a watering issue at the site. The deweeding activity was done in both the plots. Plants like Pentas, Jamaican Blue Spike and Periwinkle were seen flowering during the last visit on 5 March 2016.
A sapling count was also done on 5 March 2016 by Ms Priti Choghale, Project Manager, LEC with the help of volunteers to check the survival rate of the saplings. It was observed that 1764 saplings were surviving. It was also observed the few plants which were thought to be dead earlier like Madhumalti have sprouted back and also few laburnum saplings. Also new shoots of Bryophyllum were seen growing. The list of Plants with the survival rate in attached as Annexure 1 and comparative photographs as Annexure 2
Following are detail observations, plot wise.
Plot 1: It looked very dry with ground covered with dry leaves. It seemed as if the plants were not watered regularly. The Jamaican Blue spikes saplings were looking wilted. There were empty patches observed in the plot as seen in the images. The same could be the result of deweeding. The plants like Pentas, Jamaican Blue Spike, Periwinkle and Plumbago were flowering. It was observed that the leaves of the Laburnum saplings were eaten by caterpillars indicating the presence of caterpillars in the habitat. The Bryophyllum saplings too showed the sign of caterpillars feeding on them. New shoots of Bryophyllum were observed and have covered the ground making a carpet. Overall the habitat is established inspite of loss of plants.
Plot 2: The plants are growing well in the Plot 2 however the growth rate. Also this area being open from all sides is vulnerable to cattle attack. The MNP officials have been informed about the status of the plots on timely basis. Due to human resource and water shortage, they are unable to take care of all green zones at MNP.
1.2 C.D. Deshmukh Udyan
It was observed that the overall saplings which have survived are flourishing well and Periwinkle was in full bloom. The plants like Jamaican Blue Spike which were trimmed have grown back and have started flowering. However the garden was facing water shortage for past two months which has affected the plants drastically. The replantation work which was pending has been completed.
A total of 2836 saplings were counted during the visit and are surviving. The list of Plants with the survival rate in attached as Annexure 1 and Plot wise photographs are attached as Annexure 2
A sapling count was done on 6th March 2016 to check the survival rate of plants. Ms. Priti Choghale, Project Manager and Ms. Prabha Vannier, Environment Officer, LEC conducted the count.
2. BUTTERFLY DIVERSITY
A total of 30 species of butterflies were observed at MNP and C.D. Deshmukh Udyan.
2.1 MNP: The butterfly survey was carried out at MNP during the review visits and 24 species of butterflies were observed during the survey. Following is the list of butterflies sighted.
|Sr. No.||Butterfly Name||Number of Butterflies|
|19||Small Salman Arab||9|

Butterfly predators such as Calotes were also observed hiding among Jamaican Blue Spike plant, trying to catch the prey and thus completing the food chain in the habitat. Other insects like carpenter bee and dragonflies were observed hovering on the flowers and basking on the plants.
- Plant Count: As the plantation was done with an aim of developing an ecosystem therefore the plants were planted closely. After a year, one could see the ecosystem is well established, however the challenge is to count the creepers, climbers and stragglers which have overgrown on each other making the count difficult. Monsoon will be the right time to assess the growth of the habitat as many dying plants may spring back.
- Water Shortage: There is a water shortage experienced at both the sites and there is a concern over survival of the plantation till monsoon. The authorities at both the sites are managing larger green spaces including our butterfly habitat so the impact of water shortage is affecting overall green spaces managed by them. The concerned departments are have their internal issues to deal therefore seeking an exclusive focus to our habitats is getting difficult. Additionally the project did not have budget allocation for after care therefore we are dependent on the site partners who are trying their best but are falling short for various internal problems which we cannot be aware of.
- Mortality Compensation: As a remedy, we will develop saplings from the mature plants during the monsoon and compensate for any mortality. The clippings of most of the species planted in the habitat could be used for making new saplings.
The survival rate of sapling has gone down due to the watering issues at both the sites. The site partners have agreed that they will take care of the issues however during the summer season due to the harsh heat there may be a decrease in the survival rate. Fortunately most of the plants can be grown by cuttings. Hence the dead ones can be replaced by cuttings on the onset of monsoon.
