Wood pasture is a rare and precious landscape, home to a number of threatened species. Courtesy of the PTES, we look at a few facts about the endangered landscape, and the creatures who rely on it
- Did you know there is a strong correlation between the age of a tree and high species richness?
- At least three-quarters of the 18 British bat species will use tree holes for their summer and winter roosts.
- In Britain, the rarest and most threatened saproxylic invertebrates (these are dependent on dead or decaying wood) are found in historic parkland and open wood pasture.
- Deadwood, which is found on wood pasture sites, is more alive than living wood - a living tree trunk is around five per cent living cells per volume, in comparison to 40 per cent per volume in a dead tree.
- There are more than 2,000 different invertebrate species in Britain - 650 of which are in Ireland - which are completely reliant on deadwood.
- There are no reliable statistics on the extent of the overall condition of wood pasture and parkland, nor any historical or current rates of degradation. A figure '10-20,000 ha currently in working condition' was given based on the habitat statement of the UK Biodiversity Steering Group report, and is the current best estimate.
