Oldhouse Warren, in the heart of Worth Forest has some of the richest mycological diversity in the Weald.
Fungi play an important role in the ecosystem of Worth Forest, in both the soil and the trees. Fungi are crucial in decomposing organic matter and releasing nutrients, which are then available to other species. Without fungi, the soil would not be able to support the forest's vegetation and animals.
Fungi also have a symbiotic relationship with the trees and plants in the forest. Through the process of mycorrhizae, fungi form a mutually beneficial relationship with the roots of trees, helping them to absorb water and nutrients from the soil. This symbiotic relationship is essential for the health of the forest.
A group of Sussex mycologists are involved with recording fungal biodiversity at the site, with regular planned visits throughout 2023. Please see The Sussex Fungus Group for more information. These conditions are given by an intimate mixture of layered sands and clays, sometimes dry, sometimes soggy, sometimes acidic, sometime neutral or even calcareous, with impacted drainage . They nurture a complex mixture of fungi-rich broad-leaved trees like Birch and Beech, Oak and Alder, with Scots Pine and other conifers like Norwegian Spruce, Western Hemlock and Larches.
