NatureServe Status

Global Status: G2G3
Global Status Last Reviewed: 18Oct2017
Global Status Last Changed: 07Mar2017
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G2 - Imperiled
Reasons: Abies bracteata is endemic to the Santa Lucia Mountains of California. There are eighty known occurrences, but one is extirpated. The species is threatened by an increasing risk of fire.. This species tends to have poor regeneration rates and has a late age of reproduction, which can make recovery with increased fire frequency challenging.
Nation: United States
National Status: N2N3

NatureServe Global Conservation Status Factors

Range Extent Comments: Abies bracteata is endemic to California and known only from the Santa Lucia mountains along the south-central California coast (Monterey and San Luis Obispo counties).

Area of Occupancy: 26-125 4-km2 grid cells
Area of Occupancy Comments:  

Number of Occurrences: 21 - 80
Number of Occurrences Comments: There are eighty occurrences but one is extirpated.

Number of Occurrences with Good Viability/Integrity: Some (13-40)

Overall Threat Impact: High - medium
Overall Threat Impact Comments: Potential threats to Abies bracteata include inappropriate fire regime and roads. This species occurs in areas that are not typically at risk of fire and it is not tolerant of fire but it is thought that fuel loads are increasing in some areas due to dieback of oaks (Sudden Oak Death), putting this species at greater risk of fire. Threats to this species are exasperated due to the species late age of reproduction and poor regeneration rates. The species seeds are are parasitized by chalcid wasps which can effect the viability of a large portion of the seed crop in some years (Rogers 1998).

Short-term Trend: Unknown
Short-term Trend Comments: There are 10 occurrences with poor viability and one is extirpated.

Long-term Trend: Unknown
