Regional Scale Ecological Risk Assessment Using the Relative Risk Model

Regional Scale Ecological Risk Assessment Using the Relative Risk Model

As debates over how relative risk can be used to shape landscape-scale environmental management intensify Regional-Scale Risk Assessment demonstrates the capabilities of RRM using nine case studies in the Pacific Northwest Pennsylvania Brazil and Tasmania. The authors use a process of ranking and filters to interrelate different kinds of risks and illustrates how these relative risks are defined mapped and analyzed to determine remediation and management priorities. This book provides detailed descriptions for each step of RRM-from the determination of assessment goals to documentation evaluation and communication with decision-makers-that can benefit practitioners in environmental risk assessment and related fields worldwide. | Regional Scale Ecological Risk Assessment Using the Relative Risk Model

Tree Fern Dicksonia Antractica Log

Tree Fern Dicksonia Antractica Log

Tree ferns were a firm plant hunter's favourite from Victorian times, a symbol of wealth and travel experiences to Australia. They have maintained this sense of mystique ever since. Now you too can grow these surprisingly easy and exotic looking plants too.Harvested under strict license from woodland clearance in Australia and Tasmania, these astonishing plants really will delight and amaze. They grow under the woodland canopy, in the shade, so grow them here in a sheltered spot too. These 'potter' logs are already over 10 years old, and have been cut back and harvested dormant. When you water them via the top crown, they will burst back to life, like it's the new rainy season! Because they grow in leaf canopies, most of their food comes from leaves falling into their giant shuttlecock like fronds, funnelling the goodness into the growing crown. Even at this size of log at 30cm tall, new fronds of almost 1m in length will unfurl spectacularly in time. It's amazing when they come how quickly they grow.The plant is hardy down to -5C in winter, although the fronds will die back. Cutting these off when they die back is what creates the new trunk, which slowly inches up over many, many years. Keep the crown protected in winter with a layer of straw or wrap in a layer of horticultural fleece to keep cold and wet out. When you get it home, plant it in a big pot, or in the garden soil. Supplied dormant, with fronds that unfurl with time. Some may take up to two months for notable growth, but trust us, the wait will certainly be worth it!
