KZN Atlas Report 3-Aug-11 to 17-Aug-11

The big news is that we are at 88.7% coverage, with 90% now within imminent reach.
What is even more encouraging is that we are also steadily increasing our two and seven card coverage as well, having moved from 57.2% to 57.6% and 21.1% to 21.3% respectively.
These may not sound very high, but they represent 5 and 3 pentads, which if you do the multiplication, means 10 and 15 submissions. I know that this does not necessarily mean that there were 25 submissions for these 8 pentads, but the assumption is that there could have been 25 cards submitted. In fact in the last two weeks we had 87 cards submitted. So in effect we are not only breaking new ground and increasing depth of coverage, but also targeting that depth fairly well.
In the last two weeks we have had 18 submissions which have contributed to the 'Cards-to-Green' effort. This has moved us from needing 2 361 cards, to 2 343. The only movement has been in the 3 and 4 cards needed categories, i.e. pentads that had no or only 1 card.
Looking at total submissions, we averaging 8.1 cards submitted per day. For the last two weeks we had a submission rate of 7.7 cards and 4.7 cards per day for the respective weeks. It would seem that the cold weather in the last week has really affected submissions. With the onset of spring we also experiencing higher species totals, with 56.1 and 50.3 spp/card in the last two weeks against 45.6 and 52.0 spp/card in the previous fortnight.

KZN Atlas Report 8-Jun-11 to 3-Aug-11

During these 56 days we have had 10 new pentads added to the KZN total. Leading the charge were John and Kim Cox who completed four of these, followed by Alan Manson who did three, and then Duncan McKenzie, Colin Gerrans and myself who did one each.

Moving to the 'Cards to Green' effort,I have not been keeping absolute track of who has been doing what, but the biggest movement has also been in the north east, and glancing through the lists, John & Kim Cox's names have been appearing very regularly.

At 8-Jun, KZN was short of 2 442 surveys to turn the entire province green on the coverage map. At 3-Aug we needed 56 cards less. Besides the 10 cards in new pentads, we also had 18 fewer pentads needing 3 cards. This is quite an achievement, because it means that we submitted 28 cards for pentads needing three cards. We now have 18 less, plus the ten that had no cover, i.e. for every pentad with no data that we submit a card for, we increase the number of pentads for which we need three cards.

For this reason we now have 8 more pentads which need two cards to turn green. We can pat ourselves on the back however, since we actually reduced the number of pentads that only need one card by three.

On average we have been submitting 1.4 cards per day that contribute towards the 'KZN Cards to Green' mini-project.

Just to put a geographic perspective for  which degree squares these 81 cards to green have been submitted [the Degree Square followed by cards]:

2832 14
2831 12
2930 12
2730  8
2931  8
2632  7 [Only counting those in KZN]
2929  6 [Only counting those in KZN]
2830  5
2732  4
2731  2 [Only counting those in KZN]
2829  2 [Only counting those in KZN]
3029  1 [Only counting those in KZN]

If one looks at the accompanying map, you can see the development of a contigously atlased block stretching north from Mtunzini north along the N2. This could quite easily rival the block along the N3 stretching north-west from the coast.

Thanks to all who have are participating in the project, lets keep up the good work.

Cards to Green for KZN

This is the 'Cards to Green' map for KZN as at 22/06/2011.

We are slowly closing out the red pentads [those with no cards].

In fact, since 11/05/11 we have had 42 cards submitted that have improved this map, with 12 cards in new pentads and 12 second cards. This has meant that we now have 234 pentads that need 2 cards against 224 on 11/05. We have however reduced the number of pentads that need one card from 111 to 109, but considering that as the number of pentads that need 3 or four cards is reduced, this figure usually rises, we are doing pretty well.

An interesting stat is that over these 42 days we have averaged 1.6 cards per day for pentads with less than four cards.

Cards to Green for KZN

This is the 'Cards to Green' map as at 11/05/2011.

We are progressing quite well, with an ever diminishing number of red pentads [those with no surveys].

The greatest recent effort has been Tim Wood, Don Leitch & Gavin Calverley's expedition based at Babanago, from where they surveyed 19 pentads, 15 of which were in blank pentads.
Atlasers who have also been chipping away at the red squares are:
Alan Manson who has done 5 new pentads since March, 4 in the Tugela Valley and one west of Bergville;
John & Kim Cox with 3 east of Imfolozi Park;
Iain Guthrie, Duncan McKenzie, Mike Cunningham and Peter Spence with one survey in various corners of the province.

Thanks also to the many atlasers who have been steadily chipping away to turn this map less colourful - our ultimate goal would be to turn this whole map blank. We have 168 pentads with no cards left in KZN, and to reach 4 cards for every pentad, we need another 2 486 cards.

Cards to Green Maps

I have had a request from Peter Nupen [the Western Cape co-ordinator] for this map for the Western Cape as well.

In keeping with stressing the importance of having at least four surveys for statistical analysis to be done for a pentad, I have created this map showing which pentads in KZN have four or less surveys.

The colours used are as follows:

RED pentads have no surveys, so another four are required;

YELLOW have one survey, so need another three;

GREEN have two, so only need another two;

BLUE have three so only require one more.

In an effort to ensure some seasonality in the coverage, I have also excluded all pentads with a survey returned for autumn [basically Mar, Apr or May].

So if you are getting out further afield this autumn, or in the string of public holidays coming up, please consider using this map to plan your birding.
