It includes published literature as well as important unpublished reports. In some cases, author’s abstracts, summaries, conclusions, or selected passages were excerpted. Many reports, especially reports before 1980, were annotated to be included in the bibliography. The focus of this bibliography is on fire effects in natural forest stands. Fire impact in cut-over stands (McRae et al. 2001) is not covered, nor are the biological and silvicultural effects of broadcast slash burning (e.g., McRae 1979). The report is patterned after Schrige and Penderis (1978) in which a specific geographical area is covered. It is intended to be a handy reference for Ontario land managers, researchers, educators, and university students. It includes several references on fire effects that came from Drysdale et al. (1974). His report originated from a joint Canada-Ontario research committee and was the first recorded attempt to pull together references on fire effects in Ontario. Historical Fire Incidence The annotated portion of this bibliography does not include references related to the historical incidence of fire in Ontario. A comprehensive review on this subject was conducted by Alexander (1980). An atlas of fires greater than 200 ha, that date back to 1926, was produced by Donnelly and Harrington (1978). Several reports have examined historical fires in conjunction with specific parts of the boreal forest in Ontario. Johnston and Sharpe (1923) produced a forest survey report that included fires in northeastern Ontario. Forest age distributions and rates of disturbance in northwestern Ontario were examined by Suffling et al. (1982). Simkin (1965) reported on specific fires related to woodland caribou in the Hudson Bay Limits. In the Great Lakes - St. Lawrence Forest Region, Brunskill and Schindler (1971) studied fire history in western Ontario and Battson (1983) examined it in northeastern Ontario. Other papers (Table 1) examined average fire rotation periods in various forest zones. Table 1. Fire rotation periods in Ontario and adjacent areas.

Reviews on fire ecology in the Great Lakes - St. Lawrence Forest Region include Heinselman (1981a, b) and Wright and Bailey (1982). The ecological significance of fire was summarized in an unpublished paper by Van Wagner (1981). He pointed out that fire is one of the three primary physical factors, along with climate and soil, that have shaped the Canadian forest. In its natural state, most of the forest is dependent on periodic fire for its long-term stability. In this role, fire acts as a recycling agent. He suggested that fire is neither “good” nor “bad”. The real degradation of forest or site by fire is usually associated with repeated fires at abnormally short intervals or fires resulting from human activities such as logging. On the average, in otherwise undisturbed forests, the post-fire stands are similar and equal in quality to the pre-fire stands (Van Wagner 1981). Wright and Heinselman (1973) briefly summarized the effects of fire as an ecosystem process with several summary points. They stated that fire influences the physical-chemical environment, regulates dry matter accumulation, controls plant species and communities, determines wildlife habitat patterns and populations, controls forest insects, parasites and fungi, and controls major ecosystem processes and characteristics. Alexander and Euler (1981) reviewed the ecological role of fire in the uncut boreal mixedwood forests of Ontario by drawing upon literature from across North America. The authors used the summary points from Wright and Heinselman (1973) to organize their review paper. They completed their review by adding sections on management implications and needs and opportunities for future research. Additional selected examples of the ecological role of fire in the boreal and Great Lakes - St. Lawrence forest regions include: Ellis (1911), Candy (1939), Hustich (1957), Horton and Brown (1960), deVos (1962), Cumming (1972), Heinselman (1975), Foster and Morrison (1976), Day (1982), Klein (1982), and Cayford and McRae

    AGENDA ITEM C-2 Public Works STAFF REPORT Environmental Quality Commission Meeting Date: 12/11/2019 Staff Report Number: 19-012-EQC Regular Business: Issue Determination on appeal of staff’s approval of one heritage tree removal permit at 614 Laurel Ave. Recommendation Staff recommends the Environmental Quality Commission (EQC) deny the appeal and uphold staff’s decision to approve the permit application to remove a blue gum eucalyptus at 614 Laurel Ave. Policy Issues Under the heritage tree ordinance in the Menlo Park Municipal Code, any resident or property owner may appeal a heritage tree permit decision to the EQC. In addition, any resident or property owner may appeal the decision of the EQC to the City Council within 15 days after commission’s decision. Tree removal decisions made by staff, the EQC, or City Council must be related to the decision-making criteria in section 13.24.040 of the heritage tree ordinance. Background The City adopted its heritage tree ordinance in 1979 to ensure the large population of healthy trees are protected for a long term. The purpose of the ordinance is to: • Protect numerous oak, bay and other trees in the City • Preserve the trees for the health and welfare of the community • Prevent erosion of topsoil and sedimentation in waterways • Provide shade and wildlife habitat • Reduce air pollutants • Decrease wind velocities and noise The ordinance was created to protect and preserve heritage trees on private property by requiring a permit for removal, and only allowing removals if there is a good cause.

  • Wood Decay Fungi
    Decay Fungi Associated with Oaks and Other Hardwoods in the Western United States. Jessie A. Glaeser, USFS, Northern Research Station, Madison, WI 53726 ([email protected]) and Kevin T. Smith, USFS, Northern Research Station, Durham, NH 03824 ([email protected]) An assessment of the presence and extent of the wood decay process should be part of any hazard tree analysis. Identification of the fungi responsible for decay improves both the prediction of the consequences of wood decay and the prescription of management options including tree pruning or removal. Until the outbreak of Sudden Oak Death (SOD), foresters in the Pacific Northwest emphasized conifer diseases and decay with little attention to hardwood pathology. The SOD outbreak has drawn attention to hardwood tree species, particularly for the urban forest in which native or introduced hardwoods may predominate. Consequently, the hazard tree specialist needs a working knowledge of the fungi associated with hardwood decay. We present here some of the common fungi responsible for decay of hardwoods, particularly of oak, tanoak (Lithocarpus densiflorus), and chinquapin (Castanopsis spp.) in the West. Identification of wood decay fungi is made a little easier through grouping wood decay fungi by habitat, spatial position, and the appearance of the decayed wood (Tainter and Baker, 1996). Some wood decay fungi are saprotrophic and attack wood in service or felled logs, slash, or snags (Toupin et al., 2008). Pathogenic wood decay fungi are sometimes placed in convenient categories such as heartrot fungi (that can decay heartwood in living trees despite tree-produced protective chemicals and low oxygen conditions (Highley and Kirk, 1979), saprot fungi (that decay sapwood exposed by more-or-less recent mechanical injury), and primary pathogens that directly kill living sapwood cells in advance of infection (canker rot and many root rot fungi) (Shortle et al., 1996).

  • Silvicultural Guide for Northern White-Cedar (Eastern White Cedar)
    Silvicultural Guide for Northern White-Cedar (Eastern White Cedar) General Technical Report NRS-98 2012 United States Forest Northern Department of Agriculture Service Research Station ABSTRACT Northern white-cedar (eastern white cedar; Thuja occidentalis L.) is an important tree species in the northeastern United States and adjacent Canada, occurring both in pure stands and as a minor species in mixed stands of hardwoods or other softwoods. Yet practitioners have little and often contradictory information about cedar ecology and silviculture. In response to this information need, a group of university and government researchers in the United States and Canada embarked on more than a decade of collaborative research; this guide is a compilation of the knowledge generated by that effort. It includes an overview of the commodity and non-commodity values of cedar, silvics of cedar and companion species, descriptions of the cedar resource in the northeastern United States, Quebec, and Ontario, and silvicultural guidelines based on previously published literature and new studies of cedar regeneration, growth, mortality, site relationships, and responses to treatment. With generally slow growth and little to no ingrowth on most inventory plots in the region, silvicultural prescriptions that explicitly address cedar are warranted. Recommendations include retaining and releasing cedar in managed stands, as well as establishing and protecting advance cedar regeneration and residual trees during harvesting. Partial cutting (e.g., the selection or irregular shelterwood method) is suggested for regenerating stands with a component of cedar, though browsing by white-tailed deer (Odocoileus virginianus Zimmermann) may infl uence treatment outcomes and must be considered. Once established, cedar responds well to release and will benefi t from competition control and thinning.

  • State F O Rester Fo
    STEM DECAYS Introduction Wood decay is caused by fungi that use the woody cell wall material as a food source. These fungi inhabit and break down the heartwood of living trees, and both the heartwood and sapwood of dead trees. With the exception of several root decay and sap rot fungi, decay fungi do not attack living tissue. They break down the wood, producing a decay characteristic of the fungus. All conifers and broad-leaved trees are susceptible to decay organisms. Some decay fungi are restricted to one, or a very few tree species, while others attack a wide range of species. Wood decay organisms are an important factor in forest ecosystems because they: Remove woody debris from the forest thereby reducing the buildup of fuels and the risk of fire.

DIRECTOR MUCHof the silvical information on our for- est trees is widely scattered and some- times difficult to find. To make this material more readily available, the Forest Service is assembling information on the silvical charac- teristics of all the important native forest tree species of the United States. It is ex- pected that this information will be published as a comprehensive silvics manual. This report presents the silvical charac- teristics of one species. It contains the essen- tial information that will appear in the general manual but has been written with particular ref- erence to the species in the Northeast. Similar reports on other species are being prepared by this Experiment Station, and by several of the other regional forest experiment stations. ADRIAN M. GILBERT received h~sBachelor's degree in forestry at the Univers~ty of Michigan in 1943. Joining the North- eastern Forest Experiment Station in 1946, he served in the Forest Survey of the Northeast. In 1948 he took a year's advanced study at the Swiss Federal Institute of Technolo~y at Zurich, Switzerland. More recently (1957-58) he has been studying for a doctorate at the State University of New York College of Forestry at Syracuse. Since 1952 he has conducted research in the silviculture and management of northern hard- wood forests. At present he is in charge of the Northeastern Station's research center at Burlington, Vermont.
