Guide to Street Tree Removal the Following Identifies the Pro Cess of Removing a Public Tree guide to Street tree removal The following identifies the process of removing a public tree. City of Oregon City, Community Development Department, 221 Molalla Avenue, Suite 200, P.O. Box 3040, Oregon City, OR 97045, (503) 722.3789 www.orcity.org The first step to tree removal is to decide if the tree is located on your property or if it is located on City property. Trees located on City property (including most trees within planter strips) are street trees, which are owned by the public and require approval by the City to remove. If the tree is not a street tree, approval by the City is needed only if your property is historic, commercial, currently in land use review, and/or near a stream or slope. If you would like to remove a tree that is not a street tree or you have any questions regarding the street tree removal process, please contact the Planning Division at 503.722.3789. Step 1: Determine the Number of Replacement Tree(s) Now that you have determined the tree you would like to remove is a street tree, it is time to think about replacement. If a letter is submitted to the City from a certified arborist stating that the tree you would like to remove is dead, diseased or hazardous, the tree may be removed and replaced one for one with a single tree. or If a letter is not submitted to the City from a certified arborist determining that the tree is dead, diseased or hazardous, the tree may be removed but must be replaced with multiple trees. The number of replacement trees is based on the caliper (diameter) of the tree that you would like to remove. If you do not have enough space to plant the number of replacement trees adjacent to your property, alternative locations may be approved. Replacement Schedule for Trees Not Determined to be Dead, Diseased or Hazardous by a Certified Arborist Diameter of tree to be Removed Number of Replacement (Inches of diameter at 4-ft height) Trees to be Planted Less than 6” 1 Tree 6” to 12” 2 Trees 13” to 18” 3 Trees 19” to 24” 4 Trees 25” to 30” 5 Trees 31” and over 8 Trees or In some rare situations, an entire subdivision was planted with an inappropriate tree species, chosen by the developer. Since this time the City has adopted a street tree list of appropriate species for each planter strip width. The Community Development Director at the City may approve a one for one replacement for subdivisions planted with inappropriate tree species. or If your planter strip is two feet in width or less, the Community Development Director may approve a one for one replacement with an appropriate species designed for the planter strip width or a donation of $375 into the Oregon City Tree Bank (described in Step 3). Step 2: Determine the Species of the Replacement Tree(s) To assure the replacement tree(s) do not lift or cause damage to adjacent sidewalks, we adopted a list of appropriate tree species for each planter strip width. The replacement tree(s) must be either from: The Street Tree Planting List – A list created to assure that the tree is not fruit bearing and that the root systems do not lift nearby sidewalks. You may plant a tree species identified for your planter strip width or a narrow planter strip width. or Street Tree Removal Process An Arborist Letter – You may plant a tree species which is not listed on the Street Tree Planting List, if a letter from a certified arborist is submitted to the City specifying an alternate species that does not bear fruit and which the roots will not damage any nearby curbs, sidewalks, etc. when the tree is full grown. The replacement tree(s) must be a minimum of 1.5-inches in diameter measured 6 inches above the root crown and installed to City specifications. Step 3: Determine the Location of Replacement Trees The replacement tree(s) should be planted on the City property adjacent to your home. If there is not enough room to plant the replacement tree(s) in the public property next to your home, the City can provide you with alternative planting locations to choose from. You many want to consider installing a root barrier or planter box to limit the spreading of the roots of your new tree. In order to prevent a future problem, please assure that the tree(s) are not planted within: Fifteen feet from streetlights; Five feet from fire hydrants; or Twenty feet from intersections. Where tree replacement is dangerous or hazardous, the Community Development Director may approve a donation of $375 into the Oregon City Tree Bank rather than replanting a tree. The City will subsequently utilize the tree bank funds to purchase and plant a tree on public property. Step 4: Submit your Proposal to the City Once you know the species and location of the replacement tree(s) please submit the following to the Planning Division, located at 221 Molalla Avenue, Suite 200: - A map of your property identifying the tree to be removed; - Either: A letter from an arborist determining that the tree is dead, diseased or hazardous, or A letter identifying the diameter of the tree you would like to remove and the associated number of replacement trees; or Written approval by the Community Development Director indicating one for one replacement for an entire subdivision. - A map of the proposed location where the replacement tree(s) are to be planted. The map must also include the species and diameter of the replacement tree(s) 6-inches above the root crown. Once you submit your information to the Planning Division, a letter of approval will be sent to you at no charge. The existing tree may be removed and the replacement tree replanted after you receive an approval letter from the City. The Public Works Division at the City will locate public underground utilities at no cost by calling 503.246.6699. The City receives many calls regarding street trees and the approval letter provides surety to you and your neighbors that your plan was approved. Failure to replant the specified number of trees will result in court action. Step 5: Completing the Process Please contact the Planning Division at 503.722.3789 after the replacement tree(s) have been planted for a final inspection. After inspection you will receive a second letter indicating completion of the process and thanking you for hard work.

The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only

  • Details of Important Plants in Rpbg
    DETAILS OF IMPORTANT PLANTS IN RPBG ABIES BRACTEATA. SANTA LUCIA OR BRISTLECONE FIR. PINACEAE, THE PINE FAMILY. A slender tree (especially in the wild) with skirts of branches and long glossy green spine-tipped needles with white stomatal bands underneath. Unusual for its sharp needles and pointed buds. Pollen cones borne under the branches between needles; seed cones short with long bristly bracts extending beyond scales and loaded with pitch, the cones at the top of the tree and shattering when ripe. One of the world’s rarest and most unique firs, restricted to steep limestone slopes in the higher elevations of the Santa Lucia Mountains. Easiest access is from Cone Peak Road at the top of the first ridge back of the ocean and reached from Nacimiento Ferguson Road. Signature tree at the Garden, and much fuller and attractive than in its native habitat. ACER CIRCINATUM. VINE MAPLE. SAPINDACEAE, THE SOAPBERRY FAMILY. Not a vine but a small deciduous tree found on the edge of conifer forests in northwestern California and the extreme northern Sierra (not a Bay Area species). Slow growing to perhaps 20 feet high with pairs of palmately lobed leaves that turn scarlet in fall, the lobes arranged like an expanded fan. Tiny maroon flowers in early spring followed by pairs of winged samaras that start pink and turn brown in late summer, the fruits carried on strong winds. A beautiful species very similar to the Japanese maple (A. palmatum) needing summer water and part-day shade, best in coastal gardens. A beautiful sight along the northern Redwood Highway in fall.

  • Folivory of Vine Maple in an Old-Growth Douglas-Fir-Western Hemlock Forest
    3589 David M. Braun, Bi Runcheng, David C. Shaw, and Mark VanScoy, University of Washington, Wind River Canopy Crane Research Facility, 1262 Hemlock Rd., Carson, Washington 98610 Folivory of Vine Maple in an Old-growth Douglas-fir-Western Hemlock Forest Abstract Folivory of vine maple was documented in an old-growth Douglas-fir-western hemlock forest in southwest Washington. Leaf consumption by lepidopteran larvae was estimated with a sample of 450 tagged leaves visited weekly from 7 May to 11 October, the period from bud break to leaf drop. Lepidopteran taxa were identified by handpicking larvae from additional shrubs and rearing to adult. Weekly folivory peaked in May at 1.2%, after which it was 0.2% to 0.7% through mid October. Cumulative seasonal herbivory was 9.9% of leaf area. The lepidopteran folivore guild consisted of at least 22 taxa. Nearly all individuals were represented by eight taxa in the Geometridae, Tortricidae, and Gelechiidae. Few herbivores from other insect orders were ob- served, suggesting that the folivore guild of vine maple is dominated by these polyphagous lepidopterans. Vine maple folivory was a significant component of stand folivory, comparable to — 66% of the folivory of the three main overstory conifers. Because vine maple is a regionally widespread, often dominant understory shrub, it may be a significant influence on forest lepidopteran communities and leaf-based food webs.

  • Acer Griseumgriseum Paperbarkpaperbark Maplemaple
    AcerAcer griseumgriseum PaperbarkPaperbark maplemaple Acer griseum(paperbark maple) naturally occurs in the mountains of inland China and was brought to Veitch Nurseries in England by the botanist E.H. Wilson in 1901. There, the tree was further cultivated and introduced in Europe. The paperbark maple is a slow grower, and reaches heights up to 9 metres with a round, half-open crown. In April, Acer griseumblooms hanging, daffodil-coloured corymbs. These are discrete, but with their high nectar value, bees and butterflies are always able to find them. The hairy, toothed, compound leaf buds orange and turns a matt green with a blue-green underside in the summer. The autumn colour is spectacular, with warm orange and scarlet hues. The tree gets the name paperbark maple from its red-brown, beautiful peeling bark, which particularly stands out in the winter. Acer griseumis great for use in parks, central reservations and containers. But it also thrives in large and small (roof) gardens and in cemeteries. Plant the tree in a sheltered area in the sun or partial shade. The paperbark maple thrives in nutrient-rich, permeable sandy soil with an acidic to neutral pH value. The tree cannot handle lime very well. With its slow growth, pruning is not necessary. Dead branches can be removed.
