“…For example, element (2, 3) in (1) describes the probability that a large seedling would be damaged and thus become a small seedling. Since 0.97 100 ≈ 0.05, the adult survival probability of 0.97 corresponds to approximately a 5% chance of individuals living longer than 100 time-steps (200 years) [50] .…”

The Roles of Dispersal, Fecundity, and Predation in the Population Persistence of an Oak (Quercus engelmannii) under Global Change

A species’ response to climate change depends on the interaction of biotic and abiotic factors that define future habitat suitability and species’ ability to migrate or adapt. The interactive effects of processes such as fire, dispersal, and predation have not been thoroughly addressed in the climate change literature. Our objective was to examine how life history traits, short-term global change perturbations, and long-term climate change interact to affect the likely persistence of an oak species - Quercus engelmannii (Engelmann oak). Specifically, we combined dynamic species distribution models, which predict suitable habitat, with stochastic, stage-based metapopulation models, which project population trajectories, to evaluate the effects of three global change factors – climate change, land use change, and altered fire frequency – emphasizing the roles of dispersal and seed predation. Our model predicted dramatic reduction in Q. engelmannii abundance, especially under drier climates and increased fire frequency. When masting lowers seed predation rates, decreased masting frequency leads to large abundance decreases. Current rates of dispersal are not likely to prevent these effects, although increased dispersal could mitigate population declines. The results suggest that habitat suitability predictions by themselves may under-estimate the impact of climate change for other species and locations.

“…These masting frequencies were based on 16 years of Q. engelmannii acorn productivities (Koenig, personal communication), and on masting frequencies reported in [54] . Although we do not consider episodic bursts in germinability, our masting scenarios lead to episodic recruitment, which may occur in Quercus species [50] .…”

“…By 1986, interest had increased as indicated by attendance at the Symposium on Multiple-Use Management of California's Hardwood Resources, held at California Polytechnic State University in San Luis Obispo, California. Attended by more than 500 participants, the symposium presented 72 reports and 12 posters. In their preface to the published proceedings of the conference, Plumb and Pillsbury (1987) stated:…”

California's hardwood resource: status of the industry and an ecosystem management perspective

In an earlier publication on California's forest-zone hardwoods, 22 reasons were offered for the failure of a sustained hardwood industry to develop. This report presents knowledge developed over the past 18 years on each of these reasons. Progress is reflected in society's shift from a negative to a positive attitude towards the hardwood industry, better estimates of the inventory base and resource values, the advent of small portable sawmills, better lumber drying schedules and equipment, and recognizing the need to furnish promotional material to architects, wholesalers, retailers, and consumers. Realization that the many and complex hardwood ecosystems have value far beyond wood products has led to a new management perspective with four essential parts: emphasis, scheduling, silviculture, and total yield. Hardwood management in the near future will reflect a broadened emphasis on wildlife, water, esthetics, and wood. Desired ecological types will be needed on a schedule involving their timely creation, maintenance, and manipulation over the landscape in perpetuity. Silviculturists will achieve these ecological types, and the resulting amenities and commodities should serve rural California well.
