National Arborists

This website is for those who have trees, tree care problems, or those seeking general information on tree services. On the left-hand menu of any page, visitors will find such information as diseases, insects and removal, as well as information on identification, care and pruning. Visitors shouldn't miss the link for Sudden Oak Death, which is under the "Tree Diseases" section. The link explains that Sudden Oak Death is a disease that has killed several different types of oak trees in California, and one of the first symptoms of the disease is a dark red sap that is exuded from dark spots on the bark. The photos in the link show trees that look remarkably like they are bleeding. Also, suggestions on preventive measures to attempt to control the disease are offered. The "Tree Insects" section has links to four insects which wreak havoc on trees, along with detailed photos and prevention or eradication measures.
