Interim Chalara Control Plan
1. Reduce the Rate of Spread • Review the ban on import and movement of ash trees by Spring 2013 New legislation from 29 Oct 2012: • Prohibits import of ash trees or seed intended for planting into GB • Prohibits movement plant-passported ash trees or seed within GB • But continues to allow import of ash logs, woodchip and firewood from EU countries • And continues to allow movement of all ash timber within GB 4

Interim Chalara Control Plan
1. Reduce the Rate of Spread • Explore options for management of infected trees • Continue to inspect nurseries and require destruction of infected stock • Continue to trace recently planted stock derived from infected sources • Further work to assess the costs and benefits of tracing and destroying recently planted ash trees • Currently no action on mature infected trees but seek to assess spore production under different management regimes

Managing Infected Leaf Litter
Once infection has been confirmed… • Consider risk of spread to other areas • If disposal appropriate, then seek to prioritise on-site disposal options over movement and destruction elsewhere

Managing Infected Leaf Litter Disposal options in decreasing order of preference: • Burn on site • Burial in ground • Incineration or landfill off-site • Composting or other biological treatment off-site
Avoid moving ash leaves other than for destruction where possible 13
