Agriculture and Environmental Surveillance and Monitoring

Agriculture and environmental supervision and monitoring represent crucial steps when implementing a sustainable project. Consequently, UDA can rely on its multidisciplinary team comprised of experts in agriculture, terrestrial and aquatic biology, environment and forestry in order to satisfy any specific need. Our team of experts can develop surveillance/inspection and monitoring programs specifically adapted to client needs, reality, specificities and scope of a project, applicable regulatory framework, and particularities of project insertion environment. On the site, our experienced team ensures that construction activities are compliant with all applicable environmental laws and regulations and with the requirements of environmental permits and authorizations. Following construction or implementation works, our team carries out rigorous monitoring activities to ensure efficiency of the environmental protection measures implemented during the construction or implementation works.

  • Monitoring of water quality.

Typical projects : Agriculture and Environmental Surveillance and Monitoring


Gas Exploration and Operation Sites

Gas exploration and operation sites are often located within agricultural or agroforest territories. The implementation of a site being mostly or entirely of a temporary status, appropriate measures must be undertaken to make sure that lands recover their full agricultural potential and capabilities once the project has reached the end of its expected timeline.

UDA has elaborated mitigation measures and conducted agricultural and agroforest surveillance for several companies (Soquip, Talisman, Gastem, Forest Oil, Questerre and Canbriam) as part of the implementation of their gas exploration and operation activities in Quebec. Moreover, UDA supervised the rehabilitation works and monitored crop yields on the sites requiring complete or partial restoration.

Valorization of Fertilizing Residuals (FR)

The agricultural valorisation of fertilising residual matters are subject to a MDDELCC certificate of authorization and must be carried out according to the guidelines stipulated in the Guide for the agricultural valorisation of FR.

During spreading activities, UDA verifies that regulatory conditions prescribed by the certificate of authorization are met. Surveillance activities include the following: respect of buffer distances, location of drinking water wells and other sensitive water bodies, calibration of spreading equipment, dosage of FR for each parcel, monitoring of soil and weather conditions, ownership of access ways, etc. When specific events occur, an environmental monitoring is also carried out to verify the anticipated results.


Pipelines construction requires that agricultural, forest and environmental surveillance be conducted by an experienced inspection team. UDA can rely on a highly skillful team and carried out several mandates of this type in much diversified environments. As part of these projects, UDA was responsible for the application of mitigation measures such as: modification and repair of subsurface drainage systems, compliance with clearing limits, protection of top soil, methods for watercourse crossing, separation of the various soil horizons when excavating, cultivated soil decompaction, implementation of specific measures for construction within sensitive areas, seeding, etc.

Moreover, UDA is able to conduct all kind of environmental monitoring following final rehabilitation of work areas in order to verify the efficiency of the mitigation measures implemented during construction. UDA may also recommend practical corrective measures based on its extensive experience in this field of activities.

Transplantation of a Species with a Particular Status

UDA performed a major environmental monitoring project following the transplantation of a species at risk, which had been found during the inventories preceding the construction of a pipeline. 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. A five-year monitoring project leads to the conclusion that transplantation was highly successful.

Maintenance of Pipeline Systems

After obtaining the required permits and authorisations, UDA may, in association with its clients, carry out environmental surveillance during maintenance activities and environmental monitoring of sites. During these activities, UDA ensures that mitigation measures specific to each site are implemented for agricultural, forestry and environmental components. Its comprehensive on-site experience allows UDA to propose practical and specific mitigation measures for events that could occur during these activities.
