Home gardens are the first source of immediate contact between people and plants since the gardens are within homesteads. Most home garden studies in Senegal concentrate on food security and economic benefits; no research has been carried out on the social and ecological contexts of home gardening in Senegal. It is therefore necessary to evaluate the way people interact with the home garden plants and how such an interface influences plant diversity. The objective of this study is to evaluate the ethnobotanical knowledge associated to home garden plants and its effect on plant diversity conservation in home gardens. A sample of 30 home gardens was selected from the three main departments of the region and was used to collect plant species data. Data were collected from informants who were selected basing on recommendations from village leaders. Techniques used were plant inventory, participatory observations and individual interviews. Species nomenclature was based on Senegal analytical flora and the world plant list; comparison of effect between different variables was analyzed in analytical software R using simple linear regression analysis. A total of 96 plant species were identified; all species were found to be useful plants divided into eight functional groups. Fifty-four percent (54%) were food species, 40% medicinal, 32% ornamental, 14% commercial, 7% fodder, 4% sacred, 4% ceremonial and 3% cosmetic. Citrus limon was the most frequent (80%) and preferred species in the home gardens. Food plant species are the most diversified, abundant and rich use category. There is a relationship between uses of species and species diversity (P value < 0.001). Species diversity in the home gardens increases as the spectrum of use increases; thus, species with more than one use were highly diversified; people prefer multipurpose species for multiple benefits. This study expresses home gardens as diversified agroecosystems for sustainable biodiversity conservation of useful plant species.

塞内加尔蒂斯地区家庭园艺植物物种的民族植物学知识及其对家庭园艺植物多样性的影响

家庭花园是人与植物直接接触的第一个来源，因为花园位于宅基地内。塞内加尔的大多数家庭菜园研究都集中在粮食安全和经济效益上；没有对塞内加尔家庭园艺的社会和生态环境进行研究。因此，有必要评估人们与家庭花园植物互动的方式以及这种界面如何影响植物多样性。本研究的目的是评估与家庭花园植物相关的民族植物学知识及其对家庭花园植物多样性保护的影响。从该地区的三个主要部门中抽取了 30 个家庭花园的样本，用于收集植物物种数据。数据是从根据村领导的建议选择的知情人那里收集的。使用的技术是植物清点、参与式观察和个人访谈。物种命名法基于塞内加尔分析植物群和世界植物名录；使用简单线性回归分析在分析软件R中分析不同变量之间的效果比较。共鉴定出96种植物；发现所有物种都是有用的植物，分为八个功能组。百分之五十四 (54%) 是食用种类，40% 药用，32% 观赏，14% 商业，7% 饲料，4% 神圣，4% 礼仪和 3% 化妆品。柑橘柠檬是家庭花园中最常见（80%）和首选的物种。食用植物种类是最多样化、最丰富、用途最丰富的种类。物种利用与物种多样性之间存在关系（P 值 < 0.001）。家庭花园中的物种多样性随着使用范围的增加而增加；因此，具有不止一种用途的物种高度多样化；人们更喜欢多用途物种以获得多种好处。本研究将家庭花园描述为多样化的农业生态系统，用于有用植物物种的可持续生物多样性保护。
