Mapping impacts of Phytophthora austrocedri in juniper

Carried out by: Centre for Ecology and Hydrology/Forest Research/University of Cambridge

Summary Description:

A key component of resilience of forest ecosystems to pathogens is understanding environmental and ecological processes that favour establishment and spread for effective targeting of mitigation methods.

Such conditions are poorly described for new oomycete Phytophthora pathogens that are damaging forest ecosystems in Britain.

Phytophthora austrocedri is now known to be causing extensive dieback of Juniper, a declining UK Biodiversity Action Plan priority species, in Scotland and northern England.

This project aims to (1) determine how topography, climate, hydrology and host community structure interact to favour disease establishment and spread from field scale to landscape and regional scales (2) understand how conditions favouring juniper population persistence interfaces with conditions favouring disease establishment and (3) develop spatial tools that map P. austrocedri impact on juniper populations for geographical targeting of conservation and biosecurity measures.

Timescale: 2017-2021
