Data from: Trends in habitat quality and habitat degradation within terrestrial protected areas

Please see the paper "Trends in habitat quality and habitat degradation within terrestrial protected areas" for the definition of habitat quality, habitat degradation and different threats.

This dataset describes global habitat quality and degradation for 2020, with a resolution of 250 m. Values of habitat quality and total habitat degradation can be used directly. Of note, values of habitat degradation caused by each threat should be multiplied by the relative threat weights before use.  The details are as follows:

1. "quality_c_2020.tif" represents habitat quality.
2. "deg_sum_c_2020.tif" represents total habitat degradation which is caused by all 5 threats.
3. "deg_sum_c_NonIrriCrp_2020.tif" represents habitat degradation caused by non-irrigated cropland, and should be multiplied by 0.2145 before use.
4. "deg_sum_c_IrriCrp_2020.tif" represents habitat degradation caused by irrigated cropland, and should be multiplied by 0.2292 before use.
5. "deg_sum_c_CrpVeg_2020.tif" represents habitat degradation caused by mosaic cropland-vegetation, and should be multiplied by 0.1623 before use.
6. "deg_sum_c_VegCrp_2020.tif" represents habitat degradation caused by mosaic vegetation-cropland, and should be multiplied by 0.0541 before use.
7. "deg_sum_c_Urban_2020.tif" represents habitat degradation caused by urban areas, and should be multiplied by 0.3400 before use.

Besides, "InputData_forR.zip" provides data on protected-area-level habitat quality and habitat degradation, which is for statistical analyses by R in the paper "Trends in habitat quality and habitat degradation within terrestrial protected areas".
