Risk of Introduction Top of page It is a declared B list noxious weed in Colorado and a Class C noxious weed in New Mexico, and is on noxious weed lists on a number of other states where present and invasive, e. It is soil adaptable but needs mulching in our climate to protect surface roots from dry frost. Germination and establishment of the. There are single records for Argentina and Chile and a report of it having escaped and is naturalising Klich, Nuclear DNA markers present more technical and conceptional problems but are essential for the understanding of genome evolution that underlies organismic evolution.
Elaeagnus angustifolia (Russian olive)
Additionally, mature Russian-olive exhibits several traits that allow it to thrive in grazed habitats, including sharp thorns, which increase in density if the tree is cut back, and large seeds that may enhance the survival of seedlings following browsing. Dix and others [ 54 ] suggest that grasshoppers sometimes consume leaves of young trees as well as the fleshy part of the fruit.

Sandbar willow, Russian-olive, saltcedar, Great Plains false willow Baccharis salicina , desert false indigo Amorpha fruticosa , and New Mexico olive Forestiera pubescens var. Similarly, large, well-established stands of Russian-olive are nearly impossible to eradicate throughout an entire watershed, whereas small patches of Russian-olive can be adequately controlled using a variety of control methods [ ]. Factors to be addressed before a management decision is made include inventory and assessment to identify the target weed and determine the size of the infestation s ; assessment of nontarget vegetation, soil types, climatic conditions, and important water resources; and an evaluation of the benefits and limitations of control methods [ ]. See the Weed control methods handbook for considerations on the use of herbicides in natural areas and detailed information on specific chemicals and techniques.
