15 – 28 November 2021
The month of November sees a prominent drop in temperature across India, to which tree species respond in myriad ways. The November Tree Festival (held between 15 and 28 November 2021), was an occasion to celebrate this seasonal shift, and we are excited to present this report on the event!
To make things fun, we had posed 3 tree observation challenges to SeasonWatchers –
- 100-Not-Out! – to observe 100 trees per week of the event,
- Spy the Species – to observe 10 different species per week of the festival, and
- Mango mania – to observe as many mango trees as possible
77 individuals, and 107 schools and colleges from 22 states and union territories participated in the event and contributed many wonderful observations from across the country. Citizen scientists from across India made 6238 observations on 4733 unique trees during the November Tree Festival. Of these, 3293 observations were ‘regular’ observations, while 2945 observations were ‘casual’. Like in many other challenges, Kerala contributed the most number of observations! Read on to find more about observations, challenges and challenge-winners!
L- locations of SeasonWatch observations. Darker colour indicates higher density of tree observations. R – Of the 22 states and union territories, the most number of observations came from Kerala, followed by TN, Puducherry, MP and A&N Islands.
127 of the 138 species on the SeasonWatch list were observed during the November Tree Festival! Below are some summaries of observations from different species.
L – A blooming ‘Pride of India’ from Bangalore shared by Ranjeet Kate via Twitter. Ranjeet notes that the tree has bloomed earlier than usual, R – Owing to one of the festival challenges, Mango was the most observed species of the event, followed by Jackfruit, Tamarind, Teak and Guava. Indian Laburnum, Neem, Coconut, Devil’s tree and curry leaf tree were the next most-observed tree species.
The duration of the event saw onset of winter in north while the south experienced unusually heavy rains. This varied climate led to interesting observations from different parts of the country. For example, Jackfruit trees from 6 different states displayed a diversity of phenophases. Such comparative insights on behaviour of a species in different parts of the country perfectly highlighted the need for observing tree seasonality with SeasonWatch.
SeasonWatchers contributed observations on many species from across the country. Enchanting observations on the Himalayan cherry were by Caroline Syiem from Meghalaya. This pink bloom in the northeast was matched by that of the Silk Floss tree from Bareilly, Uttar Pradesh and purple Bauhinia from Mumbai, Maharashtra.

SeasonWatchers had to observe 100 trees in each week of the event. We congratulate everyone who took up this challenge. Here are the top three individual observers who crossed 200 observations in two weeks.
Elavarasan M, who recorded 108 and 105 species in the 2 weeks of the event, is the winner of this challenge. The astounding 456 tree observations made by K. S Lyla and 209 tree observations made by Surendhar Boobalan are truly commendable.
Schools and students are the best SeasonWatchers. Here’s how schools have done in the 100-not-out challenge –

Mango trees are most thought of during the mango season. But what do they look like in the off-seasons? This challenge was to initiate a discussion about the seasonality of mango trees by observing them. Here are the top 5 individuals who observed the most number of mango trees:
|Dr.P U Priyanka||47|
|FES Bichhiya (SHT Mandla)||16|
Dr. P U Priyanka wins the challenge in the ‘individual’ category. Special mention to SeasonWatchers Subhashini Krishnan and Divya for sharing mango observations from Coimbatore, Tamil Nadu.
Subhashini Krishnan shared a flowering and fruiting mango from Coimbatore, Tamil Nadu

|Govt Higher Secondary School||72|
|Infant Jesus H S Vadayar||748|
|KPM Model School||78|
|Veeravnchery LP school||63|
Infant Jesus H S Vadayar school wins the mango mania challenge for having observing 748 mango trees during the 2 weeks of the festival.
From the data on mango trees collected by the participants of the November Tree Festival, here is the mango picture in India:
That’s all about the November Tree Festival 2021. We hope the results inspired you to start observing trees with us. SeasonWatch will be back with another tree quest in 2022. Stay tuned!
