Introduction<\/strong><\/h2>\n

Many shade-loving succulents, notably Haworthia and Gasteria, recruit beneath \u201cnurse\u201d shrubs whose canopies buffer extremes of heat, light, and herbivory. This facilitation can double or triple seedling survival relative to open ground. We examine the microclimatic and biotic mechanisms behind nurse effects and how shrub loss\u2014through browsing, fuelwood harvest, or drought\u2014can bottleneck populations of these small, slow-growing plants.<\/p>\n

The Details<\/strong><\/h3>\n

Under nurse canopies, peak leaf temperatures drop, night-time minima rise, and vapor pressure deficits soften\u2014reducing transpirational demand for seedlings with limited storage. Litter improves infiltration and provides mycorrhizal inoculum; thorny nurses physically shield seedlings from browsers. As plants mature, some transition toward more light-tolerant rosettes, but many continue to benefit from dappled light that limits photoinhibition. Spatial associations with particular shrub species suggest that canopy structure and phenology matter as much as identity.<\/p>\n

Landscape changes can sever this facilitative link. Overbrowsing removes the very shrubs that create safe sites; firewood cutting can produce \u201copen thicket\u201d where seedling recruitment collapses. Restoration can mimic nurse effects via brush-packing, shade cloth, or planting under living hedges for the first 2\u20133 years. Managing small mammal burrowers, which can uproot seedlings under shrubs, may be necessary in some sites. Nurse facilitation also helps maintain beta-diversity by allowing shade-adapted succulents to persist alongside sun-loving Aizoaceae and Aloes, enriching community structure at fine scales.<\/p>\n
