Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification wood and pulp plantations (includes afforestation) - small-holder plantations happening now small area/few individuals (<10%) no or imperceptible deterioration low
Human intrusions and disturbance recreational activities happening now small area/few individuals (<10%) no or imperceptible deterioration low
Residential and commercial development housing and urban areas happening now some of area/population (10-49%) slow but significant deterioration medium
Transportation and service corridors roads and railroads happening now small area/few individuals (<10%) slow but significant deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Little/none of site covered (<10%) No management planning has taken place Very little or no conservation action taking place negligible
