Growth of five species of trees on experimental plots on sand tailings left after mining for rutile in Sierra Leone

Data consists of the height of five species of trees after 2.5 years of growth; the five species are: ? Gmelina (Gmelina arborea), ? mango (Mangifera indica), ? cashew (Anacardium occidentale), ? citrus (Citrus sinensis) and ? monkey apple (Anisophyllea laurina). Trees were planted on the sand tailings which consit of a very coarse quartz sand (silts and clays are dumped separetly during the processing of the rutile in the ?wet plant?). The lack of本数据集涵盖5个树种生长2.5年后的树高数据，涉及的5个树种分别为： - Gmelina（Gmelina arborea） - 芒果（Mangifera indica） - 腰果（Anacardium occidentale） - 柑橘（Citrus sinensis） - 猴苹果（Anisophyllea laurina）。供试树木种植于砂尾矿（sand tailings）之上，该尾矿由极粗石英砂构成，粉砂与黏土会在金红石（rutile）湿法加工过程中被分别倾倒。本描述至此未完成，原文末尾仅为"The lack of "
