Elephant density over 40 km 2 of the Luangwa Valley was estimated as 2–17 km ‐2 to give a population size of around 86 in that area, a tally that would probably top if unsurveyed areas within the drainage had been included.

Coates J, Swindale A,Cited by: Jachmann H () Aerial Survey of the Luangwa Valley Animal Abundance and Population Trends (Luangwa Integrated Resource Development Project, Chipata, Zambia). Estimating abundance of wildlife is an essential component of a wildlife research program, and a prerequisite for sound management.

With the exception of a few highly mathematical volumes, there are no books on the subject for use by students and field workers. Also, the various techniques for counting animals found in scientific journals are often not accessible to African managers. An unmentioned limiting factor in aerial survey accuracy is that helicopters are routinely used to kill ‘exotic’ animals and predators – often while counting game.

This terrifies wildlife. Years of doing this – as in the Sierra Diablos where Circle Ranch is located – has taught sheep, deer, elk and pronghorn to associate helicopters. WLF Fish & Wildlife Population Ecology.

Fall LAB 4: AERIAL SURVEYS I. Conceptual Framework (basic problems with estimating population size) A. Observability or Sightability (B)Most methods of surveying animals do not result in counts or captures of all animals present on an area, i.e., the probability of seeing or catching an animal will generally be less than 1.

Introduction. Knowledge of species’ abundance is integral to managing and conserving populations (Williams et al. ).Passive detectors, such as remote cameras, are gaining popularity for estimating abundance noninvasively (O'Connell et al. ).However, most camera studies have applied capture–recapture models that require individually identifiable animals (KaranthBurton et al.

Journal of Applied Ecology () 39, – Introduction On the African continent, light aircraft have been used to assess the abundance of wildlife since the mids.

The first attempts aimed at total counts of animals of all species in a particular area. The Luangwa Valley lies in Muchinga, Eastern and Central Provinces of Zambia, forming an extension of the Great Rift Valley. LNP is a relatively small national park in the mid-Luangwa Valley, situated between the larger North and South Luangwa national parks on the other side of the Luangwa River (Fig.

Located in the north-eastern part of Zambia and spanning over 9, square kilometres of unspoilt African wilderness, South Luangwa is a. Selecting an appropriate method to monitor animal populations can be challenging, particularly for low‐detection species such as reptiles.

This study compares 3 detection‐corrected abundance methods (capture–recapture, distance sampling, and N‐mixture) used to assess population size of the threatened Hermann's tortoise. We compared data from “pre-COMACO” aerial wildlife surveys in and against results from surveys performed on the same flight transects in and Jachmann H.

On the basis of these data, processed in accordance with the method of the area study, the experts estimate the population index for the entire territory of the hunting grounds.

Synoptic population census counts are a fundamental tool in population ecology, but can be challenging to conduct in remote environments. Historically, aerial approaches have been appealing for research teams working in remote locations where populations are dispersed over large areas and access to breeding sites is difficult and/or dangerous (Southwell et al.).

Fish and Wildlife Service East Tudor Road, Anchorage Alaska The Luangwa Valley has a few animals that don’t live anywhere else. You can tell a Thornicroft giraffe from other giraffes by the unusual pattern on its coat. Same with the Crawshay's zebra with their distinctive stripes.

If you’re lucky, you could also see the endemic Cookson's wildebeest. Management goals for animal populations are frequently expressed in terms of population size (Lancia et al. Accurate estimates of animal abundance allow for documentation of population trends, provide the basis for setting harvest quotas (Miller et al.

), and permit assessment of population and habitat management programs (Storm et al. Distribution: Geographic area where individuals of a species occur.

Abundance: Number of individuals in a given area. Ecologists try to understand what factors determine the distribution and abundance of species. Populations are dynamic—distribution and abundance can change over time and space. ***Understanding the factors that influence these dynamics helps us manage populations for harvest.

tial to improve accuracy and precision of counts and thus estimates of population size, it could aid in tracking grazing patterns of wild and domestic animals across large natural systems. Study Areas We acquired aerial imagery across portions of Cache County (i.e., Cache Valley) and a portion of Box Elder County in northcentral Utah.

Introduction. Trypanosomiasis has been endemic in Zambia for a long time. The great African rinderpest pandemic which wiped out most of the ungulate population in the late s contributed to the decline of the wildlife and tsetse distribution in Zambia [1, 2].As a result, eastern Zambia was largely free of tsetse making cattle rearing virtually possible in the Luangwa valley towards the.

This survey is a primary method used to monitor the threatened spectacled eider population along with other species of concern such as the red-throated loon, black scoter, and long-tailed duck.

The spatial location of all observations within a given subunit was assigned to the center point of the sub. Aerial surveys also suggest overall ungulate declines in the Luangwa Valley and lower ungulate density in GMAs compared to PAs We reduced our risk of double-counting animal herds during each survey by surveying all segments over a period of 3–4 days.
