Abstract

Many selected populations from plants and animals have been frequently used as indicators species for monitoring ecological changes and ecosystems dynamics overtime, giving early warning signs for possible deviations in ecosystems, and allowing for measuring performance of management interventions. However, there is recent criticism and discussion among the environmental scientists and mangers about the pitfalls of the approach. This article aims at reviewing limitations & challenges of selecting and using indicator species in monitoring biodiversity & ecosystem changes. Particular objectives are (1) outlining and briefly discussing common challenges and limitations, (2) pointing out ways for overcoming limitations mentioned including list of best signs that must be observed and considered when identifying indicator species for monitoring ecological changes, and finally (3) providing a path for future research work needed in this topic. Literature review showed that criticism and limitations are including subjectivity and vague justifications in selecting single or group of indicators, methodological challenges during data collection, and lack of knowledge about responses of such indicators to future climate change and subsequent impacts on their effectiveness in ecological monitoring schemes. In conclusion, the best indicator species should have among others; known responses to disturbances, quickly indicate changes and cause-and-effects relationships in ecological state variables, has a stable population in space and time, and easily detected and measured. Finally, future work needed in this topic should be directed towards: (1) assessing and increasing the effectiveness of the indicators; (2) understanding the limitations of indicators including their sensitivity to anticipated climatic changes; (3) which taxonomic groups are better for which monitoring purpose; and (4) lastly, finding better quantitative multimetrics indices to assess the efficiency of the indicators.
