Survey and monitoring techniques

General Principles of Survey and Monitoring Techniques in Upland Habitats

• Surveying and monitoring are essential tools for recording and understanding the dynamics of upland habitats.
• These activities can entail the counting and mapping of plant and animal species, recording the presence of invasive species, and monitoring habitat conditions.
• Comparative studies are often conducted to understand changes over time. These involve comparing new data with historic data to notice any significant developments or declines.
• The use of technology, such as Geographic Information System (GIS) and remote sensing, has become a pivotal aspect of these surveying and monitoring practices.

Vegetation Survey Techniques

• Vegetation surveys typically involve identifying and recording the species present within a given plot, along with their abundance and distribution.
• Researchers also observe the height and growth form of vegetation, record any unusual characteristics, and note site factors such as altitude, aspect, and slope.
• The Quadrat method is a common vegetation survey technique, whereby a square frame is thrown randomly within the study area and all species within the frame are recorded. This practice can provide valuable data on species presence and abundance.
• Another method, the Transect method, involves drawing a line across the habitat and recording vegetation at regular intervals along this line. This can help in studying changes in vegetation across different habitat zones.

Wildlife Survey Techniques

• Wildlife surveys generally focus on the presence, number, and behaviour of birds, mammals, insects, and other organisms.
• Direct observation is a common method for wildlife surveys. This includes visual or auditory observation and can be done in person, or remotely using technologies such as camera traps.
• Other methods may involve the collection and examination of indirect signs such as tracks, fecal matter, feathers, and nests. This can provide information about species not easily observed.
• Tagging and tracking is another technique used to track the movement and behaviour of specific animals over a period of time. Radio transmitters, GPS collars, or simple colour bands are used for this purpose.

Considerations when Surveying Upland Habitats

• Surveys should be carefully planned and undertaken in a consistent and systematic way to ensure the data collected is accurate and reliable.
• Surveys are often conducted during specific times to coincide with the active periods of target species. For instance, bird surveys may be carried out during breeding seasons.
• The random sampling approach is commonly used in field surveys to avoid bias and ensure a fair representation of the habitat.
• Always remember to adhere to professional ethics and legal requirements, especially when handling wildlife and operating within protected areas.
