In March, look out for nesting behaviour in blue tits and great tits - record your sightings on our survey
Completely bare except for shrivelled leaves
- Use mature trees (30 years old or more), as young trees show different responses.
Even trees of the same species, close to each other can behave very differently.
Record the trendsetters
- If you are finding it difficult to decide when to record, wait until the event is occurring in three trees of the same species in close proximity to each other. Record the trendsetters rather than the extraordinary.
- Leaves may fall off before you have recorded any significant colour change. This may be the species or the weather conditions. Don’t worry! Just record when the tree is bare.
