Tree Removal / Care
While the perceived risk of death by falling trees (a part of the “tree risk” complex) is influenced by media and often hyped (the objective risk has been reported to be close to 1 : 10.000.000, almost as low as death by lightning), singular events have encouraged a “proactive” stance so that even lightly damaged trees are likely to be removed in urban and public traffic surroundings. As a tree ages and nears the end of its safe useful life expectancy (SULE), it’s perceived amenity value is decreased greatly. A risk assessment normally carried out by local council’s arborist to determine the best course of action. As with all public green spaces, trees in green urban spaces and their careful conservation is sometimes in conflict with aggressive urban development even though it is often understood how urban trees contribute to liveability of suburbs and cities both objectively (reduction of urban heat island effect, etc.) and subjectively. Tree planting programs implemented by a growing number of cities, local councils and organizations is mitigating the losses and in most cases increasing the number of trees in suburbia. Programs include the planting of 2 trees for every 1 tree removed, while some councils are paying land owners to keep trees instead of removing them for farming or construction.
Tree care is the application of arboricultural methods like pruning, trimming, and felling/thinning in built environments. Road verge, greenways, backyard and park woody vegetation are at the center of attention for the tree care industry. Landscape architecture and urban forestry also set high demands on professional tree care. High safety standards against the dangers of tree care have helped the industry evolve. Especially felling in space-limited environments poses significant risks: the vicinity of power or telephone lines, insufficient protective gear (against falling dead wood, chainsaw wounds, etc.) and narrow felling zones with endangered nearby buildings, parking cars, etc.. The required equipment and experience usually transcends private means and is often considered too costly as a permanent part of the public infrastructure. In singular cases, traditional tools like handsaws may suffice, but large-scale tree care usually calls for heavy machinery like cranes, bucket trucks,harvesters, and woodchippers.
Road side trees are especially prone to biotic stress by exhaust fumes, toxic road debris, soil compaction, and drought which makes them susceptible to fungal infections and various plant pests. When tree removal is not an option, because of road ecologyconsiderations, the main challenge is to achieve road safety (visibility of road signs, blockage-free lanes, etc.) while maintaining tree health.
Sioux Falls (/ /) (Lakota: Íŋyaŋ Okábleča Otȟúŋwahe; “Stone Shatter City”) is the largest city in the U.S. state of South Dakota. It is the county seat of Minnehaha County, and also extends into Lincoln County to the south. It is the 47th fastest-growing city in the United States and the fastest-growing metro area in South Dakota, with a population increase of 22% between 2000 and 2010.
As of 2016, Sioux Falls had an estimated population of 178,500. The metropolitan population of 251,854 accounts for 29% of South Dakota’s population. It is also the primary city of the Sioux Falls-Sioux City Designated Market Area (DMA), a larger media market region that covers parts of four states and has a population of 1,043,450. Chartered in 1856 on the banks of the Big Sioux River, the city is situated in the rolling hills on the western edge of the Midwest at the junction of Interstate 90 and Interstate 29.
The history of Sioux Falls revolves around the cascades of the Big Sioux River. The falls were created about 14,000 years ago during the last ice age. The lure of the falls has been a powerful influence. Ho-Chunk, Ioway, Otoe, Missouri, Omaha (and Ponca at the time), Quapaw, Kansa, Osage, Arikira, Dakota, Nakota and Cheyenne people inhabited and settled the region previous to Europeans and European descendants. Numerousburial mounds still exist on the high bluffs near the river and are spread throughout the general vicinity. Indigenous people maintained an agricultural society with fortified villages, and the later arrivals rebuilt on many of the same sites that were previously settled. Lakotapopulate urban and reservation communities in the contemporary state and many Lakota, Dakota, Nakota, and numerous other Indigenous Americans reside in Sioux Falls today.
