Volunteer: Report




One part of our research is to make a map over what kinds of Phytophthora exist where in the country. That can tell about the future, how the plant killer will spread or what kind of it is growing most heavily.

1. Choose a good day for an excursion.

2. Find a dying or sick looking tree. The species of the tree doesn’t matter! Use our pictures and information to recognize symtoms.
Take a picture of the crown and damages on the stem of the tree. Photo evidence and/or notes describing the symptoms and location of the dying plant is absolutely essential for SLU scientists to examine prior to going out to the site.

Note this information:
• Species
Position where the photo was taken, coordinates and/or precise information. If you don’t own a GPS, you can use your smart phone to drop a pin in Google Maps and save the coordinates (latitude/longitude), or save the pin and record the coordinates later.
Site: Did you take the photo in a city, a park or in a forest?
 The diameter of the stem 130 cm from the ground
