Monitor native grassland for evidence of shrub encroachment.
Grassland area has declined over time, and today there is very little native grassland at the preserve.
Plant and protect coast live oak to improve young oak establishment and survival.
Further research is needed to validate that the oak population is aging. If confirmed, oak seedlings and saplings should be planted and protected from cattle and other herbivores with fences.
Anticipate climate change and species range shifts.
TNC should anticipate the potential loss of some species (such as tanoak and La Purisima manzanita) and the increased occurrence of southern or heat-tolerant species (such as lemonade berry).
Conduct a detailed investigation into California red-legged frog habitat.
Jalama Creek habitat is a conservation priority due to year-round flow. However, TNC should investigate the importance of stock ponds and cattle troughs in the frogs’ distribution and habitat connectivity across the preserve.
