DescriptionService biologist Mara Alexander records data (9408865322).jpg |
Afrikaans: Elke somer fynkam 'n span bioloë van die Nasionale Parkediens, USDA Bosdiens, Archbold Biologiese Stasie, Noord-Carolina-staat en die Amerikaanse Vis- en Natuurlewediens sommige van die hoogste pieke in die Suidelike Appalache om data oor die verspreiding van die bedreigde Appalache-naelkruid (Geum radiatum) in te samel. Op hierdie pieke word mooiweer afgewissel met midsomerkoue, of met donderstorms en weerlig wat jou dwing om vinnig skuiling te soek. Die steil terrein noodsaak dikwels toue en harnasse om die plante te bereik.
Meer as tien jaar se data oor groei, reproduksie en mortaliteit help bioloë om die langtermynstatus van hierdie verspreide populasies vas te stel. Verder verkry hulle 'n duideliker prentjie van die werklike behoeftes vir 'n selfonderhoudende, lewensvatbare bevolking – kennis wat sal aandui waar toekomstige hulpbronne aangewend moet word om die spesie se lewenskragtigheid te herstel sodat dit van die lys van bedreigde spesies verwyder kan word.

Weather on these peaks varies from clear skies with bright sun, to mid-summer frigid temperatures, to thunderstorms with lightening that forces people quickly to shelter. The terrain is steep, and often ropes and harnesses are required to reach the plants.
Over ten years of data on growth, reproduction, and death will help biologists determine the long-term health of these spreading avens populations and further, it will give them a clearer picture of what is truly needed to have a self-supporting, viable population - knowledge which will direct where future resources are devoted in the effort to recover this plant and remove it from the endangered species list.
