Complete Montesclaros Declaration
Prepared by a group of more than 70 forest pathologists (representing 17 nations) that attended an international
meeting held at the Montesclaros Monastery in Cantabria, Spain during May 23th - 27th, 2011.
As scientists studying diseases of forest trees, we recognize that the international
trade of plant material is increasing the risks to forest health worldwide.
The evidence for this view is based on the recent, unprecedented rise in numbers of alien pathogens
and pests emerging in natural and planted forest ecosystems in all parts of the globe.
We thus propose a phasing out of all trade in plants and plant products determined to be of high risk
to forested ecosystems but low overall economic benefit.
We regard all international trade in containerized ornamental plant seedlings and trees
intended as plants for instant landscape planting as low benefit in terms of overall economy
but high risk to forest health. For instance, production of seedlings in low cost localities
for outplanting in different and distant environments provides only a marginal net economic
benefit to the whole area, but provides an efficient pathway for pathogen and pest dispersal.
In addition, international trade in other plant materials (e.g., wood packaging, wood chips, etc.)
should be scrutinized and more strictly regulated.
