明尼苏达州has long offered license plate options that feature the state’s natural resources. A new design highlights the state bee, the rusty patched bumble bee, and state butterfly, the monarch butterfly. The license plate also features a native plant, the purple prairie clover, which is an important food source for pollinators such as bees and butterflies.
The rusty patched bumble bee was listed by the US Fish & Wildlife Service as an endangered species in the lower 48 states. It is currently known to occur in Illinois, Indiana, Iowa, Maine, Massachusetts, Minnesota, Ohio, Virginia, West Virginia, Wisconsin and Ontario, Canada. Population surveys suggest the abundance of this species has declined 87% in the past two decades and occupies only 0.1 % of its historic range. Many potential factors are hypothesized as reasons for the bee’s decline including habitat loss, pesticide use, disease, and climate change. There are almost 20 species of bumble bee native to Minnesota, and the rusty patched bumble bee is the first that has been formally added to the federal list of threatened and endangered species.
君主蝴蝶是一种着名的物种，在整个下的48个州和加拿大南部都发生了广泛。这种物种对于昆虫来说是显着的，因为它从加拿大和美国迁移到墨西哥的过冬地区。每个成年蝴蝶都需要四到五周，因此需要多一代完成年度迁移周期。最近审查了君主蝴蝶，以回应提交给美国鱼类和野生动物服务的请愿书列出威胁或濒危物种。该服务拒绝列出2020年12月20日的保护物种，尽管它指出，最近在濒危物种法案下的物种公正上市的丰富下降。由于其他物种的优先表现较高的优先级，列表被排除。该服务将每年审查该状态。许多影响生锈斑纹的斑纹蜜蜂的压力也会影响顽固的杀戮，如栖息地丧失，杀虫剂和气候变化。
Braun Intertec提供的许多自然资源服务之一是筛选提议的manbetx手机网项目，以潜在影响威胁和濒危物种。manbet体育滚球任何评估的第一步是桌面审查。我们咨询州和联邦数据库以确定项目区域中已知受保护的物种，然后使用空中照片和现场照片来确定网站上存在什么类型的栖息地。这一步骤赞美Braun Intertec提供的现有服务，这些服manbetx手机网务需要现场访问，例如I阶段环境网站评估和manbet体育滚球湿地描绘。有关土地利用和陆地覆盖的注意事项与照片和空中照片相结合，提供了有价值的信息，以帮助我们的科学家描述栖息地或潜在栖息地。
The next step in our assessment is to compare the list of possible protected species and their habitat requirements with the list of habitats present. Frequently, we can make a definitive determination that a given endangered species is not present because the habitat is not present. In fact, most reviews for protected species end there. Because of past land use or disturbance, it may be obvious that there is no way a species could utilize that land as habitat – such as tree-roosting bats on sites with no woody vegetation or aquatic species on sites with no lakes, rivers, or ponds. Occasionally, our consultants find that the habitat of a species could be present on a site, and site surveys by a knowledgeable biologist may be required. If a protected species is present and may be impacted by a project, we can assist with obtaining an Incidental Take Permit and developing appropriate avoidance and mitigation measures.
In the case of the rusty patched bumble bee, we use methods developed by the Xerxes Society and recommended by the US Fish & Wildlife Service to evaluate the likelihood of appropriate habitat being present. These methods consider site conditions such as the presence of native plants and natural plant communities which will have the greatest abundance of floral resources that the bee depends upon. Other important factors are the presence of sites for underground overwintering burrows, and inhospitable land use such as turfgrass, impermeable land cover, and areas of pesticide use. Offsite factors are also important, such as nearby undeveloped land or native plant populations. These factors are considered because bees are mobile organisms and exist in regional populations that may utilize foraging and burrow habitats across multiple sites.
与威胁和濒危物种的传统观点不同，生锈的斑纹腮腺蜜蜂和帝王蝶的发生经常与人群相对应。天然植物在景观中的越来越普及为这两种物种以及数十种的其他花粉师提供了重要的栖息地和资源。这种与一些受保护的物种形成鲜明对比，例如灰熊或佛罗里达州海牛，与荒野或独特的栖息地有关。
When habitat for protected pollinators is found on a project site, we offer recommendations to avoid or minimize impacts to these pollinators, such as retaining areas of native plants, or recommendations to enhance their habitat, such as incorporating native plants into landscape designs.
