Cleft Bramble

The Cleft Bramble, Rubus laciniatus, known also as the Cutleaf or Evergreen Blackberry, is a vigorous, thorny shrub in the family Rosaceae native to central and southeastern Europe, from the Balkans through to southwestern Asia. It is widely naturalized in western North America, southern Australia, New Zealand, and other temperate regions where it was introduced as a garden plant or for erosion control. The distinctive deeply divided, laciniate leaves with finely cut leaflets distinguish it from other brambles. Like other Rubus species, it produces edible black fruits relished by birds and mammals, making it an important food plant for wildlife, but its vigorous growth and ability to root from stem tips make it an aggressive colonizer and a serious invasive species in many regions outside its native range. In the Pacific Northwest of the United States, Rubus laciniatus forms dense, impenetrable thickets that displace native vegetation and reduce biodiversity. Control is difficult given its extensive root system and the ability of fragments to regenerate. The species is listed as a noxious weed in several US states and Australian states. In its native European range, Cleft Bramble is not threatened and occurs in woodland edges, hedgerows, and scrubby habitats.

Comet Darner

<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.
