Best Management Practices for Tree Removals in Parks and Protected Areas

Ministry of Water, Land and Air Protection, Parks and Protected Areas Branch (2004)

BC Parks recognized the need to remove trees from parks for a variety of reasons including hazard mitigation, pest management, road development and restoration of native disturbance regimes in fire-regulated ecosystems. When it is necessary to fall trees within parks, the primary objectives are to minimize the ecological damage caused by the operation and to ensure that the site is rehabilitated as quickly as possible. DHC researched and produced a series of guidebooks that establish the standards, objectives and Best Management Practices for removing trees within provincial parks and protected areas. The following three guidebooks were developed: Planning Guidebook, Forest Road Design and Engineering Guidebook, and Harvesting Operations Guidebook. Their purpose is to provide government staff and contractors with comprehensive guidelines, ensuring that all tree removal projects are executed in compliance with both BC Parks policies and all provincial and federal legislation. They place an emphasis on practices that identify and protect all critical ecological features.

City of North Vancouver, Master Plan for Urban Forest Management

City of North Vancouver (2006)

The City of North Vancouver hired DHC to complete a comprehensive inventory and management strategy for their natural areas. A strategic document was created to address the access and recreation concerns of the public while meeting natural areas conservation policies. This project, which included 13 parks, was divided into three components: the development of a detailed ecological inventory, detailed prescriptions to sustain the ecological integrity of the parks, and fire management plans. Most of the parks in the City run adjacent to streams and creeks and therefore riparian areas management was focused upon in all management recommendations.

City of Burnaby, Urban Parks Inventories and Management Plans

City of Burnaby (2006)

DHC completed comprehensive ecosystem inventories and forest management strategies for a number of the City's natural areas and parks. The plans included ecosystem mapping, ecological health assessment and prescriptions for their enhancement and long-term integrity. In addition, wildfire management plans were completed for these parks that include strategic fuels treatments to reduce the long-term risk in hazardous interface zones.

Walton Park, Management Plan

City of Coquitlam (2007-2008)

Walton Park is a new protected area that was severely damaged by the winters windstorms of 2006-2007. DHC was hired to assess the ecological characteristics of the forest, consult with the City and the public and make recommendations for its restoration and future management. Issues of concern included the cleanup of the windthrow areas, tree hazard management, public safety and invasive species management. A Park Management Plan was developed that specifies restoration treatment prescriptions as well as detailed recommendation for trails and facilities.

Burnaby Central Park, Inventory and Regeneration Plan

City of Burnaby (2005)

DHC was asked to identify those processes that are impacting forest succession and to make recommendations to ensure that the ecological integrity of the Park is maintained. The Park was delineated into ecotype polygons with similar stand and ecological characteristics. Within each unique polygon, tree characteristics were collected including tree species composition, stocking density, diameters and heights, age classes, live crown ratios, and total crown closure. The sites were also classified according to the Biogeoclimatic Classification System of BC. During the field assessment, special care was taken to look for the presence of any pathogens of concern, sensitive or unique ecological features, endangered plants, fauna or plant communities.

The inventory was used to develop stand enhancement prescriptions to restore the long-term health of these forests. Strategies included monitoring and control of forest pathogens, planting and brushing to promote a healthy understory, rehabilitation of degraded areas as well as a hazard tree management plan.

District of North Vancouver Fromme Mountain Ecosystem Analysis

District of North Vancouver (2004 - 2005)

The North Shore has become recognized as one of the best locations for mountain biking in the world. As such, there has been a dramatic increase in the demand for, and subsequent building of, mountain bike trails and structures. This has presented a serious challenge to the District of North Vancouver in terms of managing the associated liability and impacts to the surrounding environment.

DHC developed an ecosystem ranking system to help manage recreation while protecting key ecological features in the Fromme Mountain Area. Existing GIS databases, orthophoto analysis and representative ground plots were compiled and an ecosystem ranking system was developed. Five critical indicators were given a numeric ranking that increased relative to their ecological value or sensitivity. Their rankings added together to produce a final ecological analysis map. This map helps to envision the collective sensitivity and level of biological diversity found in each forest stand type. Based on these findings, draft recreation management zones were recommended.

Green Timbers Urban Forest and Sunnyside Acres Urban Forest, Ecosystem Based Access and Recreation Management Plans

City of Surrey (2002 - 2003)

DHC prepared management plans for Surrey's two largest Urban Forests. These documents proposed specific actions to address the access and recreation concerns of the public and stakeholders while preserving the ecological integrity and heritage values of the forests. An inventory of the ecology and habitat was conducted to determine the impacts on various trails and activities. All trails, their permitted use, conditions and maintenance requirements were inventoried, as well as the signage and facilities in and surrounding the parks.

This provided a foundation from which various options of trail use and their locations were considered with the preservation of the ecological integrity and heritage values as the limiting factors. A consistent signage theme was recommended, which included reducing the 'sign pollution', and suggesting locations for new signage and facilities to meet the needs and reduce the conflicts associated with its users.

This report included extensive consultation with various City employees, the Parks Advisory Committees and numerous user groups and stakeholders. In addition to the consultation noted above, a survey of park users and local residents was conducted to establish the needs, wishes and concerns associated with its use. This information was compiled to help determine appropriate trail designs, locations, and their permitted use and associated signage and facility requirements.

Port Kells Park, Management Plan

City of Surrey (2003)

DHC Ltd was asked to assess the local and regional significance of the ecology and habitat found at Port Kells Park. This assessment was conducted to determine whether access and recreation in the park was feasible while protecting its critical ecology and wildlife habitat. It involved classifying the forested ecosystems into polygons based on similar ecology, stand history and forest type by air photo. Further analysis lead to field visits to collect information pertaining to vegetation cover, critical wildlife habitat, significant natural and cultural features and fire hazard. The data was then compiled into a GIS based inventory system and rare and endangered plant and animal species were identified as listed by the Conservation Data Centre of BC. Recommendations were made with respect to potential recreation and access developments, future park acquisitions in adjacent areas, fire hazard abatement and the protection of rare and endangered species.

Proposed Port Mann Park, Ecology and Wildlife Habitat Assessment

City of Surrey (2002, 2006)

The City of Surrey recognizes the need to identify and protect essential ecological features within their parks system in order to conserve ecological biodiversity on a regional and provincial scale. DHC was approached to develop an ecological inventory, identify critical ecological features, and make recommendations to assist in the planning of the proposed Port Mann Park.

A GIS based ecological inventory was completed for the proposed park that included classifying the ecology to the biogeoclimatic classification of BC, inventorying critical habitat characteristics, stand attributes and describing the understory vegetation. This inventory and field reconnaissance was used to analyze the stand dynamics and seral stage distribution and to identify critical wildlife habitat and rare and endangered plant communities in the proposed park. The existing trails were assessed and recommendations were made to assist in developing an access and recreation plan for the proposed park.

GVRD Seymour/Capilano Filtration Project, Rehabilitation Strategy

GVRD (April 2003 - Present)

DHC is working with landscape architects to develop comprehensive habitat rehabilitation strategies for the filtration project. Prior to clearing of the site, an ecological inventory was developed that accounted for features such as soils, understory vegetation, coarse woody debris and stand structure and composition. This inventory was used to produce a biodiversity/ecosystem ranking for each inventory polygon based on six recognized critical ecological attributes. The combined ranking for each polygon was multiplied by its total area to produce an overall value for the ecosystems impacted by the project. This ranking system was summarized into an ecological balance sheet that was used to set targets for the rehabilitation phase of the project.

Rehabilitation strategies include the salvaging of topsoils, forest floor and coarse woody debris from the site, the creation of wildlife trees through gilding and planting of stems and prescribing plant communities that are red and blue listed. The difference in the ecological balance sheet is compensated for through enhancement projects off site such as biodiversity thinning of second growth stands and fish stream improvement projects.

Shellburn Distribution Terminal, Development of Restoration Plan for West Creek

City of Prince George, Wildland/Urban Interface Wildfire Management Strategy

City of Prince George (2005)

A comprehensive Urban Wildfire Management Strategy was completed for the City of Prince George, providing a background review of the fire environment, the level of wildfire risk, and recommendations on how to prescribe and prioritize treatments to reduce this risk. A detailed forest inventory was completed along with this plan. This provided a detailed and accurate database that was used to evaluate the risk (fire behaviour potential) and consequence (human lives, structures and natural features) of a wildfire occurrence. This landscape level analysis identified a number of continuous hazardous fuels. Long term planning was recommended to strategically reduce the threat in these areas through initiatives such as harvesting and development planning.

In addition to a landscape level analysis, all areas that were within 100 meters of any structures where assessed for fuel loading and fire behaviour potential. These areas were ranked using a fuel hazard assessment procedure that was developed specifically for the forests found in this region. The results of this assessment were used to prioritize areas for fuel treatments.

This report also provided recommendations for future community planning and design. This included not only the treatment of adjacent vegetation but also access, water sources and standards for construction and landscaping. Broad recommendations were made to reduce wildfire threat through wildfire preparedness, public education and interagency co-operation.

Future recommendations included developing a standardized fuel treatment prescription template, establishing pilot projects for fuels treatments within the city, as well as an adaptive management strategy to incorporate new scientific knowledge and to monitor and evaluate treatments implemented to determine their effectiveness.

This landscape level analysis identified a number of continuous hazardous fuels. Long term planning was recommended to strategically reduce the threat in these areas through initiatives such as harvesting and development planning.

In addition to a landscape level analysis, all areas that were within 100 meters of any structures where assessed for fuel loading and fire behavior potential. These areas were ranked using a fuel hazard assessment procedure that was developed specifically for the forests found in this region. The results of this assessment were used to prioritize areas for fuel treatments.

This report also provided recommendations for future community planning and design, including not only the treatment of adjacent vegetation but also access, water sources and standards for construction and landscaping. Broad recommendations were made to reduce wildfire threat through wildfire preparedness, public education and interagency co-operation.

Future recommendations included developing a standardized fuel treatment prescription template, establishing pilot projects for fuels treatments within the city, as well as an adaptive management strategy to incorporate new scientific knowledge and to monitor and evaluate treatments implemented to determine their effectiveness.

EC Manning Park, Fuel Break Feasibility Study

Davies Wildfire Management (2005)

Davies Wildfire Management, Diamond Head Consulting, Tom Lacey Ltd. and Timberline completed said study in the fall of 2005. The study involved recommending locations for landscape level fuel breaks to protect the East Gate Community and the Manning Park Lodge area. Potential fuel break locations were assessed and final locations were delineated in the field. Ecologically accurate and scientifically sound fuel treatment recommendations and prescriptions were developed for each fuel break. Presentations of the work were given to the Ministry of Environment and the Manning Park Interface Committee.
