Survey Seasons

Maximising Survey Efficiency with the Ecology Survey Season Calendar

Effective ecological surveys are essential for understanding and protecting biodiversity. These surveys are critical in detecting the presence of various species and obtaining accurate ecological data. The timing of these surveys is crucial, as conducting them during optimal periods ensures higher detection rates and data reliability. This article delves into the importance of the Survey Season Calendar and how it can enhance survey efficiency.

Understanding the Survey Season Calendar

The Survey Season Calendar is a strategic tool that outlines the optimal, suboptimal, and out-of-season periods for conducting various ecological surveys. This calendar is based on the biological and behavioural patterns of different species, considering factors such as breeding seasons, hibernation periods, migration patterns, and vegetation growth cycles.

Key Survey Seasons for Different Ecological Surveys

Extended Phase 1 Habitat Survey

  • Optimal: April to October
  • Suboptimal: November to March

Bat Emergence and Re-Entry Survey (BERS)

  • Optimal: mid-May to September
  • Suboptimal: April to October
  • Out of Season: November to March

Badger Survey

  • Optimal: mid-October to April
  • Suboptimal: May to September

Breeding Bird Survey

  • Optimal: March to June
  • Suboptimal: July
  • Out of Season: August to February

Dormice Survey

  • Optimal: mid-April to November
  • Out of Season: December to March

Great Crested Newt Survey

  • Optimal: April to May
  • Suboptimal: March and June
  • Out of Season: July to February

Reptile Survey

  • Optimal: April to May
  • Suboptimal: March, October and June to August
  • Out of Season: November to February

Water Vole Survey

  • Optimal: April to September
  • Out of Season: October to March

The Importance of Timing in Ecological Surveys

Planning surveys during the optimal season significantly enhances the chances of detecting the presence of species and obtaining accurate data. For instance, conducting a bat emergence and re-entry survey during the optimal period of mid-May to September increases the likelihood of observing bat activity and identifying roost sites.

Similarly, breeding bird surveys are best conducted from March to June, when birds are most active in their nesting and breeding activities. Conducting these surveys outside the optimal period can lead to incomplete or inaccurate data, potentially impacting conservation efforts and development plans.

RSS Infrastructure’s View on Survey Season Calendars

RSS Infrastructure recognises the critical role that the Survey Season Calendar plays in conducting successful ecological surveys. According to RSS Infrastructure, the optimal survey season for bat surveys starts in May, aligning with the peak activity periods of these species. By following the Survey Season Calendar, RSS Infrastructure ensures that their surveys are conducted at times when species are most detectable, leading to more accurate and reliable data. This approach not only supports effective biodiversity conservation but also aids in the timely planning and execution of development projects.

Challenges and Considerations

While the Survey Season Calendar provides a framework for planning ecological surveys, several challenges and considerations must be addressed:

  1. Weather Conditions: Adverse weather conditions such as rain and wind can affect survey results. For example, bat surveys may be compromised if flight paths are disrupted by strong winds or heavy rain.
  2. Multiple Visits: Some surveys require multiple visits to gather comprehensive data. Coordinating these visits within the optimal period can be challenging but is crucial for accurate results.
  3. Geographic Variations: The geographic location of the survey site can influence the timing and results of ecological surveys. Local climate and habitat conditions may require adjustments to the survey schedule.

Enhancing Survey Efficiency

To maximise survey efficiency and accuracy, it is essential to:

  • Plan Ahead: Schedule surveys well in advance, considering the optimal and suboptimal periods.
  • Monitor Weather Forecasts: Adjust survey plans based on weather conditions to ensure data quality.
  • Consult Experts: Engage with experienced ecological consultants to tailor survey plans to specific site conditions and species requirements.

Conclusion

The Survey Season Calendar is an invaluable tool for planning and conducting effective ecological surveys. By adhering to the optimal survey periods, ecological consultants and developers can ensure higher detection rates and more accurate data, ultimately supporting biodiversity conservation and sustainable development.
