    Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts.

Host plant/s: European white birch, white-barked Himalayan paper birch, gray birch, sweet birch, yellow birch, cottonwood, and sometimes river birch. Description of Damage (larvae and adults): Bronze birch borers prefer trees that are stressed due to drought or defoliation. Larvae feed on the phloem and cambium while creating numerous galleries, which eventually alters nutrient transport and kills off the root system while leading to further necrosis in the major branches and main stem. Adult beetles feed on leaves but do not harm the overall health of the tree. References: Iowa State University. (2003-2016). Species Agrilus anxius - Bronze Birch Borer.

    Field Identification Guide Bronze birch borer Photograph: Karl W. Hillig W. Karl Photograph: Funded by the EU’s LIFE programme Bronze birch borer The bronze birch borer (BBB, Agrilus anxius), a beetle belonging to the family Buprestidae, is a serious North American insect pest of birch trees Betula( species). The BBB causes extensive mortality to birch populations and can attack trees with stems greater than 2 cm in diameter and branches of 1 cm in diameter. Damage is caused by larvae feeding on the inner bark and cambium of the tree. Repeated attacks and the excavation of numerous winding galleries by the larvae cause disruption to water and nutrient transportation within the tree, leading to death of tissues above and below ground. In many cases tree mortality is observed within just a few years of the appearance of the first symptoms. Species affected All species of birch are susceptible to this pest. In its natural range of North America, BBB is considered to be a secondary pest of the native birch. In contrast, Asian and European species such as our native silver and downy birch (Betula pendula and B. pubescens) are much more susceptible to this pest. Signs and BBB infestation is usually difficult to detect until the symptoms symptoms become severe because much of the insect’s life cycle is hidden within the tree; eggs are laid in crevices, the larvae feed in the inner bark and pupation occurs in the sapwood. In most cases, the beetles have already become established and have spread to new hosts by the time they are discovered.

    EXTENSION.USU.EDU Maples in the Landscape Sheriden Hansen, JayDee Gunnell, and Andra Emmertson Introduction Maple trees (Acer sp.) are a common fixture and beautiful addition to Utah landscapes. There are over one hundred species, each with numerous cultivars (cultivated varieties) that are native to both North America and much of Northern Europe. Trees vary in size and shape, from small, almost prostrate forms like certain Japanese maples (Acer palmatum) and shrubby bigtooth maples (Acer grandidentatum) to large and stately shade trees like the Norway maple (Acer platanoides). Tree shape can vary greatly, ranging from upright, columnar, rounded, pyramidal to spreading. Because trees come in a Figure 1. Severe iron chlorosis on maple. Note the range of shapes and sizes, there is almost always a interveinal chlorosis characterized by the yellow leaves spot in a landscape that can be enhanced by the and green veins.

    Bronze Birch Borer Agrilus Anxious

    Bronze birch borer Agrilus anxious Bronze birch borer is a pest of birch trees, especially white barked birches such as Betula papyrifera, B. populifolia, B. pendula and B. maximowicziana. B. papyrifera is much more tolerant of bronze birch borer than B. pendula. Adults are similar in shape Insects overwinter as to twolined chestnut borers larvae in galleries in (photo on page 49) but are the vascular system 8-10 mm long and a dull and resume feeding in metallic bronze in color. spring as the sap rises. 8 10mm Adults emerge over a period of about 6 weeks 8-10mm beginning in late May or early June when pagoda dogwood and ‘Winter King’ hawthorns are in full bloom. Females lay eggs on the bark, and larvae hatch out and begin boring into the bark around the time that European cranberry- bush viburnum or weigela are in bloom. Larvae form winding galleries in the cambium of the tree, girdling branches and disrupting the flow of water and nutrients in the tree. Larvae may take up to two years to complete their development. Lumpy branch is symptom of bronze birch borer. Bronze birch borer - continued Symptoms: Bronze birch borer injury includes dieback that begins in the upper portion of the tree, a lumpy appearance to branches where galleries are present, and D-shaped exit holes in the bark created by emerging adults. Rusty-colored stains may also be visible on bark in the area of entrance or exit holes. Management: Stressed trees are much more prone to injury. Avoid planting birches in hot, dry sites.

    Bronze Birch Borer: a Toronto Master Gardeners Guide

    Bronze Birch Borer: A Toronto Master Gardeners Guide The bronze birch borer (Agrilus anxius) is a beetle native to North America. The borers? larval feeding tunnels under the bark girdle the trunk or branch of the tree and interrupt the flow of nutrients and sap which eventually leads to the tree?s starvation. Older trees or those weakened by environmental stress or other insect infestations are most susceptible to attack. The adult bronze birch borer is a slender, olive-bronze, 10 mm long beetle. The larva is flat-headed, white and 12 mm long. The bronze birch borer can be a serious pest of several species of birch: white or paper birch (Betula papyrifera), grey birch (B. populifolia), and European birch (B. pendula). Symptoms of Bronze Birch Borer The first signs of damage by the bronze birch borer are sparse, yellowing foliage and browning tips on the upper branches of the affected tree. The dieback starts at the top of the tree and works downward. Infested branches may show swollen ridges on the bark, indicating the locations of feeding galleries (conspicuous swollen areas on the trunk are caused by the healing process of a survivor tree). D-shaped exit holes in the bark are a definite sign of the emergence of adult borers. Besides being more resistant to the Birch leafminers also turn the leaves of birch trees brown, but their damage Bronze Birch Borer. river birch (Betula nigra) features peeling bark which adds shows up throughout the tree, not only at the top.
