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
