Looking up into a tree canopy from a trout’s (or any fish for that matter) perspective, it’s easy to see why this cover is so attractive.
For a trout as possible prey, overhead tree cover provides: –
- Protection from arial predators, e.g. birds
- Some protection from land based predators, e.g. fly fishers
- Sanctuary from water based predators e.g. pike
For a trout in feeding mode, actively seeking prey, tree cover means: –
- An overhead food store at times, as bugs fall out of tree cover into the water
- Concealment from which to ambush unwary prey, e.g. small fish
- Lower light levels providing fish with the confidence to feed
Yes, it’s easy to see why trout like tree cover and why casting a fly around these areas is very productive!
