Caledon and Tynan ASSI

Caledon and Tynan is a special place because of its parkland and fen habitats. Historic parklands are generally characterised by old, open-grown trees and shrubs which have significant amounts of dead wood. These old open-grown trees provide a very specialist habitat for certain species of invertebrates, lichens and fungi, many of which are rare.

A wide variety of parkland trees and shrubs are present on the site, with significant numbers of open-grown veteran and ancient trees and shrubs.
Oak is the dominant species, with other species such as beech, hawthorn, horse chestnut and crack-willow. There are also some spectacular avenues of trees, including an avenue of ancient sweet chestnut along the canal at Tynan.

The lake at Tynan is surrounded by fen, with swamp and wet woodland. Fens are important wetland habitats that are fast disappearing from our countryside due to land drainage and pollution.
