They most frequently attack pine, birch, maple, spruce and fruit trees and do the most damage during breeding season and territory establishment between February and June. [11] Beavers girdle the bases of stems 3-6 inches in diameter, and girdle the roots of larger trees. This often weakens or kills trees.
Porodaedalea pini, commonly known as the pine conk, [1] is a species of fungus in the family Hymenochaetaceae. It is a plant pathogen that causes tree disease commonly known as "red ring rot" or "white speck". This disease, extremely common in the conifers of North America, decays tree trunks, rendering them useless for lumber. [2]
For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S. [5] [6] [7] The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas. [8] Loblolly pine is the first among over 100 species of Pinus to have its complete genome sequenced. As of March 2014 ...
Fungal diseases such as laminated root rot and shoestring root-rot can cause significant damage, and in plantation settings dominated by Douglas-fir monocultures may cause extreme damage to vast swathes of trees. [13] Interplanting with resistant or nonhost species such as western redcedar and beaked hazelnut [39] can reduce this risk.
The green pine needles give the twisted branches a bottle-brush appearance. The needles of the tree surround the branch to an extent of about one foot near the tip of the limb. [13] The name bristlecone pine refers to the dark purple female cones that bear incurved prickles on their surface. [5] [12] The dark color of these cones helps to ...
The tree has remarkable roots. Monterey pine roots will reach downward as far as physically permitted by subterranean conditions. Roots have been discovered up to 12 meters (39 ft) long. [19] Efforts to remove large quantities of the non-native tree in areas of South Africa have resulted in significant increases in accessible water. [18]
Generally, you'll apply mulch 2 to 3 inches deep, with the exception of grass clippings, which you should keep to a depth of 1 to 2 inches.. Be sure to avoid building mulch "volcanos" against tree ...
Roads, sidewalks and foundations can all suffer structural issues from tree roots. [7] Several methods of control have been attempted, from barriers to encouraging growth in desirable directs. Selection of plants with root systems that will not conflict with nearby structures is the most effective method of damage control.
