Observe the trees around you with SeasonWatch

Using citizen science to track the patterns of emergence and maturation of leaves, flowers and fruits of Indian tree species.

Climate change is experienced in the form of erratic, unpredictable and extreme weather changes in the various seasons. This is impacting the periodic appearance of leaves, flowers, and fruits on the seasonal trees around us. Observing these changes regularly can give an insight into climate change’s impact on biodiversity in India. Since trees are the basis of all life, including ours, understanding the impact of climate change on trees is imperative.

For over a decade, SeasonWatch is leading a citizen science project following the patterns of emergence and maturation of leaves, flowers and fruits (“phenology”) on common tree species of India. Seasonal phenology of trees can be affected by larger problems such as climate change and serve as reliable indicators of the same.

Contribution from the citizens in observing trees and collecting data can be an efficient way to collect large amounts of seasonality information from all over the country. The upcoming quarterly tree festival – March Tree Festival 2023 – is one such way of reaching out to more people and encouraging them to participate.

The competition has three challenges to make things exciting:

  • Observing 100 trees in 10 days
  • Collecting data on as many individuals as possible of 5 tree species with red/orange flowers
  • 8 tree species that are likely to sprout new leaves in March.

Contributors with the highest number of trees observed in the different challenges will win prizes.

“Tree watching in Kashmir is definitely a unique activity. It will clone the facts and changes of spring into education and research for sustainability”, says Akhter Hussain, Society for Env. Edu. & Development (SEED)

“The eye easily wanders to all that has lush, new and fresh leaves and the colours are indeed striking. As I consciously began looking at these trees, I realised how beautiful the early months of summer are. I wonder why I didn’t have the eye to see these things all these years”, says Suhirtha Muhil M, Project Manager – SeasonWatch

Beyond the parks and gardens, Bengaluru’s ‘wasteland’ ecosystems call for protection

Open Natural Ecosystems in Bengaluru harbour rich biodiversity. Take a look at what they hold and what we risk losing to unchecked development.

When we discuss urban nature, we often forget about real natural habitats. In Bengaluru, widely called the Garden City, most talks about urban nature focus on landscaped parks, roadside trees, and manicured gardens; in other words, artificial ecosystems designed for looks and human comfort. As lay citizens, we usually notice only such nature as we see around our homes, workplaces or other areas we generally pass by. While these places do have some ecological value, they mostly support a few highly adaptable species. This has strong negative implications for native flora and fauna that depend on open scrublands, grasslands, rocky…

The wild in the city: What citizen scientists tell us about Bengaluru’s biodiversity

Spatial and temporal biodiversity patterns, as observed by citizen scientists in the city during 2016-2025, were studied at a datajam in December 2025.

Imagine you’re out on a morning walk, phone in hand, when you spot a butterfly you’ve never seen before. You snap a photo, log it into a citizen science app, and voila! You’ve just contributed to crucial biodiversity monitoring. This isn’t just a hobby; it’s part of a global movement where ordinary people collect, record, and sometimes analyse data about plants, animals, and ecosystems. Citizen science stretches the reach of ecological research. Every observation adds to unique longitudinal datasets that reveal phenology — periodic events in the life cycle of a species — along with species distribution shifts and population…
