Die "Springbokjag met chopper"topic wat nou so lekker warm raak, gee ook baie antwoorde.

Taffie,

Hier is jou kort opstel.

Bearing in mind that the veld is a renewable resource only if it is managed properly, if the root reserves are allowed time and nutrition to build up, if the diversity of species is taken into account, and the use is managed as an entirety, WITH the herbivores utilising the veld, only then can land be utilised to it?s maximum potential.

What does this have to do with culling?, Everything. Should you have one species of animal utilising your veld, or 20 species, the management principles still have to apply. Too few animals over utilising preferred plant species for too long a period will deplete root reserves, and lead to the demise of that plant species within the boundaries set for that system. Too many animals utilising a section of veld will destroy the vegetation, damage the upper soil structure, speed up erosion to and from water points, intensify the build up of pathogens in the veld, increase the amount of parasites in the area, and so on.

This scenario then necessitates the removal of excess animals from the area. Should these animals be sheep, goats, cattle, horses or any other domesticated animal, the solution is easy, sell off the surplus before damage is done. Commercial game is completely different. The only possible way to manage the numbers is to cull. There is just no other viable alternative; the loss of the excess animals ensures the survival of the rest, whether on 1000Ha, 100 000Ha or 1millionHa, just look at how many 10?s of thousands of elephant died of starvation in Kenya due to the ?Ag shame? brigade. To leave them as the self righteous greenies would have us do would be the financial ruin of any farmer, the total collapse of any wildlife reserve and /or the decimation of entire populations of animals.

It is not only the herbivores that need to be culled. If a farmer, consortium or entity is to make a living from his herbivores, then it stands to reason that all excess numbers of predators also need to be culled. Culling is a management tool, nothing more, and nothing less. You do not even need a Settler mentality to realise this, all you need is a mind capable of understanding basic fundamentals of ecology.

Werkloosheid n Gevolg van oorbevolking Hoekom spreek net China sy bevolkingsgroei aan en nie Afrikane nie. Groenes het baie meer belangrike sake om aan te spreek ...visbronne ook.

Thanks for that Mac, that was very well put, if I may be so bold as to add a short insight/piece of advice on your completely correct info on the roots of the grasses, or plants that need careful grazing management, an interesting fact to note, particularly concerning ostrich. Although they are a very unique "game" species, that add greatly to the aesthetic appeal of a farm (and make some fairly good biltong, and the odd fresh fillet too!), an ostrich population needs to be VERY carefully managed, particularly in the drier, more arid grazing areas, or in [quote]imes of semi drought/drought. I don't know if this is a commonly known fact (please forgive me if you already know this guys), but an ostrich will remove a grass plant completely, and although you will see them "grazing" in times of "green grass", it has been my observation that as things get drier, they will pull the whole grass plant out, roots and all. I have done some culling of ostrich in the Eastern Cape, and as we always used to count, and observe before we started shooting, this was apparent. You can physically see the areas where ostrich have "grazed" during the drier periods of the year, and although not necessarily "devastating", it can definitely damage your veld.

Not to get too technical, but just for interest sake, when your carrying capacities are calculated (for those that don't know, the total number of animals that any given piece of land can sustain for a known period of time), it is super critical that the balance between your primary, secondary, and tertiary grazers, is calculated correctly, and as a general rule of thumb, it is better to err on the side of conservative ie. it is far safer to take off a couple too many, than leave them on. This may sound backwards, but it is incredibly difficult to predict accurate weather patterns over a long period of time, it is easier for your animal numbers to increase, than it is for your veld to recover over a really hard winter/dry period. Mac please correct me if you feel that my "add on" is incorrect. Again guys this is my opinion, based on my observations, and experiences.

[Mac]

Whisper,

No, you are entirely correct, the only comment I would hazard is that my experience with ostriches has been that they are primarily baseline browsers, and no real threat to well established grasses, or rhizomes, but in dry times grasses like Aristida and Cymbopogons can be uprooted, in good veld, that in my opinion is no great deal, as there will be sufficient seed reserve. They are also one of the few species capable of dispersing Themeda seed.

Management is key.

Het so bietjie die post gelees. Dit maak my trots om deel te wees van die forum as ek kyk na die bydraes hier. Daar is nie  eintlik iets nuuts wat ek kan bydrae  nie behalwe dat ek  die sienings ook ondersteun.

Paar punte.
- In my omgewing (en ek glo amper oral in kommersiele boerderygebiede) is die natuur (lees veldtoestand, kleinwild ens ) in beter toestand as 
    ooit sover huidige lewende boere kan onthou. Let wel deur die toedoen van die boere self. Want hulle is lief vir die natuur. NIE deur die toedoen  van groenes of wildsplase ens nie.

- As n groene siek word. Laat hy die natuur sy gang gaan of gebruik hy sy verstand en gaan dokter toe. Of staan ons apart van die natuur?

- Dit is n mite dat die natuur in natuurlike ewewig verkeer. Soos voorheen gese. Sy is gedurig besig met verandering en siklusse (daardie slim    ou waarvan almal op die forum praat het ook al gese dat verandering is die enigste konstante ) . Voedsel vir n spesie is die beperkende faktor. Baie kos- spesie vermeerder tot die kos beperk raak. Die lammers wat ons produseer as menslike voedselbron word deur die jakkalse gekaap as hul voedselbron.

- Ons moet gedurig oppas dat ons nie teoriee aanpas om ons te pas nie. wees objektief.

Groetnis Freddie

Sien jy's weer jou vlymskerp self vandag. 

Van die os op die jas vra Oom Tekoeza my ander dag of ons skaapboere al vir Checkers dankie ges? het vir al die goeie publisiteit wat hulle die afgelope tyd aan skaapvleis gegee het?  Elke keer wat daardie smaaklike, natuurlik geproduseerde, Karoo-skaaptjoppies op TV adverteer word, maak dit ons saak net sterker, aldus Oom Takoeza.

Mooiloop & hoop ons sien weer jou goeie insette by OTA IV.

Freddie,
              I think it could said that all species including us present commercial farmers goes about THE SURVIVAL OF THE FITTEST. All those who think they know better than MOTHER NATURE have gone.

  Mother Nature will sort all of us out.

Great Topic,

Ek geniet ook die topic. Glo dit gaan baie "afloerders" tot ander insigte bring. Hoop ten minste so!

Jy is ook reg sal ek reken dat almal deel van die natuur is is en nie net die deel daarvan gebruik wat jou pas om ander deelnemers daarvan te wil nakom nie nie.

Mooiloop

Ps. Wil net vir jou noem dat "Lower control arm" van Toyota meer kos as Landy "Diff" en moeiliker om terug te sit.

ou Taff,

. Wil net vir jou noem dat "Lower control arm" van Toyota meer kos as Landy "Diff" en moeiliker om terug te sit.

   
Toe maar...... jy moet ook maar onkostes he ...... anders gaan jy te veel belasting betaal . 
Ek het toe nog 'n Deffie gekry met 'n mooi body.Kan nou 'n ordentlike Landy oorbou van die twee. Jammer ek kon nie die Aliwal Skiet bywoon nie. Miskien ook maar goed ..... die ou rubber armpie sou my weer gepla 

groete,

Sorry for the late response Mac, I have been away fishing a tournament all weekend in the wind and rain !@#$%^%$#@! Thanks for the response, I was not aware that they were effective dispersal units for that specie of grass, you see, you learn every day! (life would be quite boring if you didn't wouldn't it?) Have you ever seen ostrich "grazing" on erogrostis? Observed it for the first time here in Natal earlier this year........

Blessings.

"SANParks caught in jackal cull row  

06 November 2010, 00:11

Parks authorities have shot and killed around 340 jackals in a controversial experiment to boost declining antelope numbers in two national parks.

Now conservationists have accused authorities of questionable scientific and ethical motives and of trying to mask an unprecedented cull as an experiment.

In May and September this year, SANParks authorities killed 132 jackal in the Karoo National Park and a further 73 in the Darlington section of Addo Elephant National Park and 139 from the Kuzuko section of the park, as part of a jackal research project.

In a brief research paper released this week, SANParks researchers explained that in certain sections of the parks, which have been earmarked for large predator establishment, they noted significant sustained declines in the populations of certain ungulate species, notably springbok.

A number of studies demonstrated that in fenced ecosystems, where larger predators were absent, jackals could become ?very significant predators? of the lambs of smaller to medium-sized antelope.

?Thus there was reason to believe that high jackal predation as a result of the predator trap was severely inhibiting antelope population recoveries in these two parks,? and its decision was made to reduce the predation pressure on the antelope by culling the jackals, abundant in the two parks.

But Bool Smuts, the director of the Landmark Foundation, which educates farmers about non-lethal predator controls, and is involved in jackal research, termed it highly unusual for parks authorities to embark on massive lethal sampling of an indigenous predator species in a national park.

?It?s inconceivable that this could have been allowed? that our national parks authority institutes such an action without a public participation process, then responds in an arrogant way, is not acceptable.

?It?s a cull they?re now trying to paint as an experiment. They seem to think jackals are the reason for springbok numbers not improving, and to some extent that may be true. But I don?t see any evaluation having been done in these parks, based on what?s actually affecting springbok numbers.

?As well as predation, have they accounted for the worst drought in 130 years? That may be why springbok numbers are not recovering. Or the role of certain management actions like fewer watering points in some reserves, and dropping or erecting fences. There are many possible reasons.?

He termed the move ?an extremely cavalier response to biodiversity management?.

Chris Mercer, of the Campaign Against Canned Hunting, slammed the ?secrecy?. ?If the explanation was that simple, why didn?t they say so from the beginning? Instead, they beat around the bush ? The public is entitled to know why they?re killing jackals.

?You could understand if it was 30 or 40 ? but this large number? That?s not culling. That?s extermination.?

Mercer said jackal were still widely regarded as vermin.

SANParks spokeswoman Wanda Mkulthulwa said: ?What does the drought and changing water infrastructure have to do with research? Why was there a need for public participation? Where is this requirement contained? Certainly not in the Biodiversity or Protected Areas Acts, which is where we derive our mandate. If there is new legislation maybe you can point us to this??

The Nelson Mandela Metropolitan University would study the stomach contents of jackal to help ascertain their role in constrained ecosystems, she said.

SANParks researchers said jackal removal had ceased in both parks. The focus was now on monitoring jackal and antelope population densities."

Ek het onlangs besef dat, as ek reg is, is "Natuurbewaring" maar rederlik nuut in die land. So 20-30 jr.

Dit terwyl landbou op `n bewarings grondslag al vir geslagte, (6 geslagte en langer) volhoubaar op dieselfde landbou eiendom beoefen word. Wie is dan die groep wat met gesag van uit `n bewarings hoek kan praat?
