A fleeting introduction to the Yorkshire Arboretum

What arboreta can provide to Plant Health Early

The Yorkshire Arboretum A Canary's Perspective

Jonathan Burton (Né Watkinson)

The Yorkshire Arboretum A relatively young arboretum nestled in 48ha of parkland amongst the Castle Howard Estate.

Ray Wood 10ha satellite woodland garden 1km away

Within our surrounds… Cryptococcus fagisuga

Dothistroma septosporum

Drepanopeziza sphaerioides

Hymenoscyphus fraxinus

Phytophthora ramorum

Poplar Cankers

Everyday diseases?

Ophiostoma novo-ulmi

Phytophthora alni

Erysiphe alphitoides

Pseudomonas syringae pv aesculi

What can an arboretum provide? A diverse range of species

Hopefully a range of genetic diversity of those species?

Detailed and kept records

A melting pot for interactions and observation

Focused attention on collections

• Monthly science and horticulture lectures

• Local School Visits

• OPAL Tree Observation Groups

• Examples of regional and national groups:

British Conifer Society British Plant Gall Society International Group of Nematologists International Dendrology Society

Animal and Plant Health Authority Event Raising public awareness of tree health problems.

• Public Engagement and Training

• Local, Regional and National Interest Groups

• Volunteers and Staff

European Mountain Ash Ringspot Associated Virus Recognising those that are unhealthy for less suspicious reasons…

The experience trialling the IPSN Plant Health Checker with volunteer teams • Beware of assumptions: - individual’s understanding - terminology - precaution • Really engages teams

• Increases understanding for necessary

protocols

Ongoing and potential benefits of being involved •The coordination of information and resources vital to the management of plant health

•Developing networks for mutual learning

Conveying and establishing phytosanitary practice

• To chisel or not to chisel? • What is best practice when there is no statutory

notice?

• Networks could provide a platform to discuss best practice

Concluding thoughts • Each hortico-botanic collection can provide important warnings

and opportunities

• Early Plant Health Warning Systems allow these canaries’ songs to be orchestrated

• Being involved with IPSN has been wholly positive for the Yorkshire Arboretum
