Five years survival and growth of Parkinsonia microphylla in arid degraded terrain of Sonora, Mexico
The Sonoran Desert has areas with land degradation of slow recovery. Recovering degraded land is key to obtaining ecosystem services. In this study the native Parkinsonia microphylla trees were evaluated for five years after their transplantation to degraded arid land, with protection against herbivory, under irrigation during the first year, and in a microclimate with branch pruning for the following four years. Irrigation was weekly or fortnightly during the first 200 days, prior to the rains. The protection was made with a plastic container, in addition to placing dry tree sticks from the site buried vertically around the plant. The microclimate was provided through scattered pruned branches on the ground in an area of 1 m2 per plant. Survival, height, and width of the plant canopy were evaluated. The survival at 200 days of the plants without protection with fortnightly and weekly irrigation was 0 vs. 100 % for the plants with protection plus irrigation treatments (χ2 66.0; p < 0.0001). Five-year survival was 50 % for the plants with protection, and 72 % for those with protection and microclimate. Plant heights at 90 days were higher for plants with protection treatments than for unprotected (p < 0.0001). Plant leaves were bigger for the microclimate protection treatment at five years (46 cm vs. 31 cm; p < 0.05). Protection against herbivory and the microclimate favor survival and growth on degraded land.

Por ello es clave recuperar terrenos degradados para obtener servicios de los ecosistemas. Con este objetivo se evaluaron árboles nativos de Parkinsonia microphylla por cinco años, los cuales fueron transplantados en terreno árido degradado, con protección contra la herbivoría, riego el primer año y microclima a partir de ramas de poda los siguientes cuatro años. El riego fue semanal o quincenal durante los primeros 200 días, previo a las lluvias. La protección fue con un recipiente plástico, además se colocaron varas secas de árboles del sitio enterradas verticalmente a la planta, circundándola. El microclima se proporcionó con ramas de poda dispersas en el suelo en un área de 1 m2 por planta. Igualmente, se evaluó supervivencia, altura y ancho del dosel de las plantas. La supervivencia a los 200 días de las plantas sin protección con riego quincenal y semanal fue 0 vs. 100 % para los tratamientos de protección más riego (χ2 66.0; valor p < 0.0001). La supervivencia a los 5 años fue del 50 % de las plantas con protección, y 72 % con protección y microclima. Las alturas de las plantas a los 90 días fueron mayores para los tratamientos de protección que para las plantas sin protección (p < 0.0001). El dosel foliar de las plantas fue mayor para el tratamiento de protección con microclima a los 5 años (46 cm vs. 31 cm; p < 0.05). En conclusión, la protección contra herbivoría y el microclima favorece la supervivencia y crecimiento en terrenos degradados.
