Agricultural and Urban Forestry

UDA offers personalized rural and urban forestry services for projects of various scopes. Its team of forestry experts (engineers and technicians) is able to carry out a wide-range of activities including impact studies, environmental management of forest land, forestry on privage lot, urban forestry, forest valuation, work supervision, site restoration and valorization of residual wastes. This forestry expertise is frequently put to good use when preparing requests for certificate of authorization, environmental impact studies, requests to the Commission de protection du territoire agricole du Québec (CPTAQ) and other regulatory or administrative requirements.

Typical projects : Agricultural and Urban Forestry


Agroforest Studies

UDA was involved in numerous agriforest  studies as part of the requests for authorization submitted to the Commission de protection du territoire agricole du Québec (CPTAQ). The forest section of these studies included an evaluation of maple syrup production capability of concerned lands or territories, an impact assessment on sugar bush or forest resources, and recommendations with respect to tree clearing and woodlot protection.

UDA also completed several agroforest studies on behalf of Monteregie MRCs (Les Maskoutains, Lajemmerais, La Vallée-du-Richelieu and Les Jardins-de-Napierville). The forest section of these agroforestry studies included the inventory and characterization of the wooded areas as well as the identification of forest stands of interest (maple syrup production, ecological value, protection and conservation). The general characterization of urban and rural wooded lands performed for the modification of the revised Regional Development Plan of the City of Longueuil is also worth mentioning.

Impact Studies in Agroforest Environment - Linear Projects

UDA was awarded several mandates to conduct impact studies in the outline of linear projects, mainly for pipeline projects with Enbridge, Gazoduc TQM, Gaz Metro, Trans-Northern Pipelines Inc., Montreal Pipe Lines Limited, TransCanada PipeLines and Ultramar. The forest section of these studies consisted in identifying routes or locations of lesser impacts on forest and sugar bush resources, evaluating the impacts on sugar bush and forest resources, as well as prescribing mitigation measures for these wooded areas.

Forest Appraisals

Over the last 20 years, UDA has been conducting forest appraisals for compensation purposes as part of linear projects (pipelines) undertaken by its clients, including Gazoduc TQM, Gaz Metro and Ultramar, which totalise approximately 1500 records. These appraisals are used to establish the amounts to be paid to landowners in compensation for any impact (standing timber, future crops and edging effect) of aforesaid projects. In addition, private forest appraisals are also conducted for transaction or dispute purposes.

Private Forest

UDA has been certified by the Agence forestière de la Montérégie since 1998 to offer technical services to private forest owners. Offered services consist in performing various evaluations as part of specific programs, preparing and updating forest management plans, preparing silvicultural prescriptions and implementation reports of prescribed works. Since its certification, about a hundred (100) clients benefited from the Quebec’s “Private Forest Support Program”.

Urban Forestry

In addition to economic appraisals of urban trees performed as part of projects or disputes, UDA was involved in the preparation of an intervention plan for urban trees associated with the infrastructure works carried out by the City of Le Gardeur as well as an urban forest characterization for the City of Longueuil.

The intervention plan for the City of Le Gardeur included a tree inventory along work site (species, sizes, general condition and distance from works), in order to identify mitigation/protection measures to be implemented to reduce the impacts of work activities on trees.

The characterization of urban forests located in Longueuil consisted in classifying urban forests, identifying exceptional forest ecosystems; specifying forest maple production, forest-fauna capabilities, ecological and conservation values of the forests; and in establishing the conservation priority for these forests.
