Essential Links

There is a vast and continually developing literature on every aspect of elm disease, much of which is freely available online.

The purpose of this brief links section is solely to support the substantive descriptions of elm cultivars by (a) giving objective views on their adaptation potential in this country; (b) providing overviews of the breeding programmes which produced them; and (c) setting out the evidence which supports their claims to resist the disease.

In the case of trees included on this site for which resistance data have not been published, the Wikipedia link at the foot of each clone-specific page gives the most dependable guidance available.

(a) UK adaptation reports

2nd update of the Elm Report by Andrew Brookes of Butterfly Conservation

(b) Breeding and testing programmes

Overview of the main breeding programmes worldwide, by Lorenzo Mittempergher and Alberto Santini

Overview of the French work with European elms

Overview of the Italian research programme (nb: limited to interspecific hybrids)

Overview of the Spanish research programme (in Spanish)

(c) Breeders’ descriptions and resistance data for individual clones
