Bioclimatic Characterisation of Specific Native Californian Pinales and Their Future Suitability under Climate Change

Area of Science:

• Ecology and Conservation Biology
• Climate Change Science
• Bioclimatology

Background:

• Climate change is altering temperature and precipitation, increasing drought risk and impacting plant survival.
• Soil moisture depletion and changing weather patterns pose significant threats to native ecosystems.
• Understanding species' bioclimatic needs is crucial for predicting their response to environmental shifts.

Purpose of the Study:

• To bioclimatically characterize ten native Californian Pinales (conifers) from 1980-2019.
• To project habitat suitability for these species by 2050 under climate change scenarios.
• To inform conservation strategies for conifer species facing climate-induced habitat loss.

Main Methods:

• Compiled species occurrence data from the Gbif database for ten conifer taxa.
• Analyzed bioclimatic data (temperature, precipitation) from 177 meteorological stations (1980-2019).
• Utilized linear regressions for climate projection and Boolean logic with Conditional Logic Operator (CON) for habitat suitability analysis.

Main Results:

• Most studied conifers are projected to experience habitat range reduction in California by 2050.
• Species are expected to shift towards more optimal climatic areas.
• Bioclimatology proves applicable for assessing future climate change impacts on species distribution.

Conclusions:

• Climate change will significantly reduce conifer habitat in California, necessitating adaptive management.
• Projected species displacement highlights the need for proactive conservation planning.
• This study provides a framework for bioclimatic assessments to support ecological integrity and sustainability.
