The various components of biological science are frequently included in the activities carried out by UDA as part of its mandates. Being for requests for authorization from municipal, regional, provincial and federal regulatory authorities, environmental characterization, assessment of potential impacts and other situations, UDA has the expertise to meet the biological science needs of its clients.
- Identification, characterization and inventory of wetlands;
- Inventory of flora, avifauna, mammal and herpetofauna species;
- Inventory of fauna and flora species with a particular status (protected by laws);
- Transplantation and monitoring of protected flora species;
- Identification and characterization of forest stands of biological interest;
- Research and monitoring of environmental compensation projects (wetlands, reforestation).
Typical projects : Terrestrial Biology
Transplantation of a Plant with a Particular Status
As part of the environmental impact study associated with a pipeline project, a colony of a species at risk was identified during site inventories. Transplantation of some 33,000 plants of this colony was carried out according to pre-established phases. The main steps consisted in delineating the plant removal zone, identifying and characterizing the receiving sites, preparing the receiving sites, extracting, planting and protecting the plants. The five-year monitoring project leads to the conclusion that transplantation has been highly successful.
Monitoring of Wetlands: Farnham Garrison
This project consisted in documenting the wetlands located on the Farnham Garrison training areas in terms of type, function, delineation, fauna and flora species, and preparing a management plan for beavers, which dams affected surface water drainage on adjacent properties and Government lands. This project led to the preparation of a wetland management program in the training areas. The main steps of the project were as follows:
- Identification, characterization and mapping of wetlands;
- Wildlife (fish, herpetofauna, avifauna, mammals) and flora (vegetal communities) surveys;
- Characterization of soils and waters;
- Preparation of the beaver management plan.
Detailed Characterization of Du Tremblay Forest, Longueuil
The project consisted in carrying out various inventories in the agricultural section of Du Tremblay urban forest in order to increase the level of knowledge and specify the location of existing wetlands. Data collection was also aiming at establishing the relations between existing wetlands and watercourses, verifying the presence of flora species with a particular status, identifying local fauna composition, as well as assessing the impacts of potential interventions to enhance this environment from fauna, flora, forest, recreational, and educative point of views. The main activities included:
- Carry out a survey of flora species designated as threatened or vulnerable, an occurrence mapping, and the identification of appropriate species protection measures;
- Characterize watercourses and wetlands and delineate the watersheds;
- Characterize the habitat of the western chorus frog including the evaluation of present populations, the delineation and description of the buffer zones required to ensure survival of the western chorus frog, and to propose measures for long-term conservation of its habitat.
