About the Ebook
During the latter part of 2009, the plant pathogen Phytophthora Ramorum was identified and confirmed present in the forests and woods of southern England. This newly recognised disease smothers and infects the tree or shrub, causing the bark to girdle and bleed, resulting in its death. Visual effects such as dieback and gingering of the foliage often become apparent at advanced stages of the initial infection.
Phytophthora Ramorum has been detected on more than hundred and fifty different species of trees and shrubs, ranging from Birch, Beech, Douglas Fir, Sweet Chestnut and Western Hemlock, to name but a few. Not all succumb to the fungus: its principal host, Rhododendrons, can become a breeding ground for the spores before being distributed by a variety of different means; via air currents, rain droplets, mists and through water systems, preferring a damp wetter climate. It also can be transported by people, animals and machinery.
Autumn 2009 saw the pathogen progress to Japanese larch trees, which produces inoculums five times more than rhododendrons, enabling the infection to spread far faster. To contain the spread, three million larch trees across the Southwest were felled between 2009-2011. This was unbeknown to me at the time, and it deeply affected my site pacific photographic enquiry and understanding of my native landscape.
