  • The Natural Choice for Wildlife Holidays Welcome
    HOLIDAYS WITH 100% FINANCIAL PROTECTION The natural choice for wildlife holidays Welcome After spending considerable time and effort reflecting, questioning what we do and how we do it, and scrutinising the processes within our office and the systems we use for support, I am delighted to say that we are imbued with a new vigour, undiminished enthusiasm, and greater optimism than ever. My own determination to continue building on the solid foundation of twenty years of experience in wildlife tourism, since we started from very humble beginnings – to offer what is simply the finest selection of high quality, good value, tailor-made wildlife holidays – remains undaunted, and is very much at the core of all we do. A physical move to high-tech office premises in the attractive city of Winchester leaves us much better connected to, and more closely integrated with, the outside world, and thus better able to receive visitors. Our team is leaner, tighter, more widely travelled and more knowledgeable than ever before, allowing us to focus on terrestrial, marine and – along with Dive Worldwide – submarine life without distraction. In planning this brochure we deliberately set out to whet the appetite, and make no mention of either dates or prices. As the vast majority of trips are tailored to our clients’ exact requirements – whether in terms of itinerary, duration, standard of accommodation or price – the itineraries herein serve merely as indications of what is possible. Thereafter, you can refine these suggestions in discussion with one of our experienced consultants to pin down your precise needs and wants, so we can together create the wildlife holiday of your dreams.

Technical Report of the International Water Security Network, Water Research Node, Monash South Africa, Johannesburg. Acknowledgements We wish to acknowledge the funding contribution of the International Water Security Network which is funded by Lloyd’s Register Foundation, a charitable foundation helping to protect life and property by supporting engineering-related education, public engagement and the application of research. We further wish to acknowledge the leadership and intellectual contribution of Chad Staddon who supported us throughout the preparation of this technical report.

Front cover photos supplied by Linda Downsborough 2016 i Executive Summary This technical report highlights key water security issues in Zambia with special reference to the Kafue Flats. It draws particular attention to issues of water availability and demand, competing water users, and institutional arrangements for securing water and associated resources. The report comes at a time when several countries in southern Africa including Zambia are negotiating trade-offs associated with developing water resources whilst trying to ensure ecosystem integrity. Such trade-offs are occurring amidst several other pressures including population growth, urbanisation, climate variability, and changing patterns of economic production and consumption.

  • Buffalo Count in Lochinvar National Park
    G.J.B.A.H.S.,Vol.3(3):122-131 (July-September, 2014) ISSN: 2319 – 5584 Efficacy of Population Estimates of Large Mammals Obtained through Ground Counts in Lochinvar National Park, Kafue Flats, Zambia Chansa Chomba1 & Tokura Wataru2 1 School of Agriculture and Natural Resources, Disaster Management Training Centre, P.O. Box 80415, Kabwe, Zambia. 2 C/O Zambia Wildlife Authority, Monze, Zambia. 1Corresponding Author Abstract A ground survey of large diurnal mammals was conducted in Lochinvar National Park, to determine population size and presence or absence of species. Strip count method was used which involved walking along transects and counting animals seen, signs such as spoors and pellets. Seven species were sighted during the survey, of which six were observed within 50m from the transect line. Eleven species were identified from animal pellets and footprints. Most sightings (80%) were recorded in the morning between 6:00 - 9:00 hrs. The distribution patterns varied as follows; greater kudu was evenly distributed throughout the woodland vegetation community. Buffalo, bush pig, common duiker, and chacma baboon were concentrated near Sebanze hill and the Fisheries Research station. Common duiker was only found near the southern boundary of the National Park. It was recommended that there should be annual ground surveys to fully understand population status and dynamics of the large mammals. Keywords:-Diurnal, Large Mammal, Survey, Population Status, Distribution, Woodland 1. Introduction Most surveys in Lochinvar National Park and the Kafue Flats in general have only covered Kafue lechwe (Kobus leche kafuensis) and wattled crane (Grus carunculatus) (Chansa & Kampamba, 2005). The population status and distribution patterns, of other species largely remain unknown.
