本文采用Braun-Blanquet植被调查法对德兰士瓦混合灌木草原Nylsvley自然保护区的植被进行了系统分类。植被类型为季节性草地和落叶稀树草原，植物群落主要有4个区系特征明显的类群：（1）在砂岩和长石地区的非石灰性桑迪土壤上的草地和阔叶稀树草原，（2）在石灰性、粘土性、洼地冲积土和白蚁灌丛上的小叶刺稀树草原，（3）在石灰性自覆盖垂直土壤上的草地和刺稀树草原，（4）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（5）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（6）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（7）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（8）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（9）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（10）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（10）在石灰性自覆盖垂直土壤上的小叶刺稀树草原，（（4）在长期废弃的原住民定居点和新开垦的土地上的次级群落。在216个样方的基础上，描述了7个一级群落，12个群落变异和4个亚变异，以及3个二级群落。调查进行了两个层次的细节，在阔叶稀树草原的生态系统研究领域进行了更详细的调查，植物区系和结构，比其他的保护区。
The vegetation of the Nylsvley Nature Reserve in the Transvaal Mixed Bushveld is classified hierarchically by the Braun-Blanquet Method of vegetation survey. The vegetation is seasonal grassland and deciduous savanna with four floristically distinct major groups of plant communities: (I) grasslands and broad-leaved savannas on non calcareous sandy soils on elevated sandstone and felsite areas; (2) microphyllous thorn savannas on calcareous, clayey, bottomland alluvial soils and termitaria thickets; (3) grassland and thorn savanna on calcareous self-mulching vertic soils; and (4) secondary communities on long abandoned native settlements and recently ploughed land. Seven primary communities with 12 community variations and 4 subvariations, and three secondary communities are described on the basis of 216 releves. The survey was carried out at two levels of detail, an ecosystem study area in the broad-leaved savanna being surveyed in more detail, floristically and structurally, than the rest of the Reserve.
