This study introduces a new survey design to improve plant abundance monitoring. The crossed design enhances biodiversity assessments, especially for difficult-to-detect or aggregated species.

Area of Science:

  • Ecology
  • Botany
  • Conservation Biology

Background:

  • Biodiversity loss necessitates accurate plant abundance monitoring.
  • Line transect sampling is common but has limitations for certain species and plot sizes.
  • Challenges include small survey plots, aggregated species distributions, and low detectability.

Purpose of the Study:

  • To develop an improved survey design for plant abundance monitoring.
  • To address limitations of traditional line transect sampling.
  • To enhance biodiversity quantification through more robust ecological surveys.

Main Methods:

  • Development of a crossed survey design.
  • Application of novel analytical methods exploiting the crossed design's information.

  • Illustration with field data from a cowslip ( *Primula veris* ) colony.

    • Main Results:

    • The crossed design provides additional information for more accurate abundance estimates.
    • The developed methods effectively handle challenges like aggregated distributions and low detectability.
    • Successful application demonstrated on cowslip population data.

    Conclusions:

    • The crossed design and associated methods offer a more reliable approach to monitoring plant populations.
    • This methodology can improve the accuracy of biodiversity loss assessments.
    • Enhanced ecological survey techniques are crucial for effective conservation strategies.
