The data gathered for this year is quite different compared to records we have for the last four years. Previous years experienced approximately 10 busy nights on which 30-50 toads were rescued, whereas this year there were around 25 busy nights on which 10-30 toads were recorded. The low and erratic rain this winter may have had a role to play in this. </P> <br> <p>If you know of any activity not reported here, please contact your nearest <a href="volunteer_groups.html" class="blank">Volunteer Group</a>.

Previous activities this year can be found in the <a href="2011_Diary.html" class="navigation">2011 Diary</a></p> </em></p> <p>Here we summarise the activities of the Volunteers in the different groups.

The toads are actively feeding and in wet weather they feed from the roads, where snails, slugs, earthworms and other delectables are easily seen. This is also a period in which many deaths occur as most toad groups are not ready with their campaigns yet. </p> <p>Theories about the toads breeding (or triggered to breed) at Full Moon or with lots of rain are thus all out of the window. The toads that have bred so far have done it in dry weather at near New Moon. Obviously we need lots more data before we can understand what makes a toad breed!</p> <br> <p>Here are the daily sightings of toads by the different groups over the breeding season so far:</p> <P><IMG align=top src="sarah/dailytotalgrps.png" height=370></P> <p>Note that almost all the activity to date was with the rains on 04 August, although Fish Hoek got going a day earlier, and many Cape Flats populations did not respond at all.</p> <br> <p><b>Rescue</b></p> <p>Each group consists of volunteers who patrol the streets on dark rainy nights, and even many other nights during the breeding period. The total time spent on rescuing toads is often not appreciated. Here are the man-hours spent patrolling by the different volunteer patrols to date this year:</p> <P><IMG align=top src="sarah/reschrspergrp.png" height=370></P> <br> <p>Here are the numbers of toads saved by each patrol this year:</p> <P><IMG align=top src="sarah/totaltoadsrescpergrp.png" height=370></P> <p> Note that some areas are busier than others. Our goal is to ensure that we have enough volunteers to keep down the death rates. These data also allow us to plan for the hotspots next year.</p> <br><p>In addition to rescuing toads, volunteers usually take their photographs. This is done carefully with a ruler in a standard pose. Toads' markings are like fingerprints. This allows toads to be compared from year to year, and thus estimates of age, distance moved and population size to be calculated. For more, and to put your own garden Western Leopard Toad onto the database, please see:<a href="http://za.ispot.org.uk/node/137767" target="_blank" class="bolder">Upload Your Toad.</a> For lots of toads it is better to submit a CD of photos see <a class = link href="guidelines.html">Guidelines for Data Collection</a>. Here are the numbers of photographs taken by each patrol this year:</p> <P><IMG align=top src="sarah/totalphotos.png" height=370></P> <br><p><strong>Status</strong></p> <p>Action by volunteers consists of three activities: 1) rescuing toads crossing roads; 2) collecting killed toads; and, 3) noting other toads not rescued or killed. (For our purposes, we consider injured toads to be rescued, unless we know that they have died, in which case they are "dead")).</p><p> The daily rescued/killed/noted toads for each group can be seen here. </p> <p>Choose a group for the status of toads over time in an area:</p> <SPAN class=titles> <A class=titles href="sarah/stateberg.png" target=_blank><BR><BR>BERGVLIET <BR></A></SPAN> <SPAN class=titles> <A class=titles href="sarah/stateclov.png" target=_blank><BR><BR>CLOVELLY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statecycl.png" target=_blank><BR><BR>CYCLE TRACK<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statedieo.png" target=_blank><BR><BR>DIE OOG<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statefish.png" target=_blank><BR><BR>FISH HOEK<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/stateglen.png" target=_blank><BR><BR>GLENCAIRN<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statehout.png" target=_blank><BR><BR>HOUT BAY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statekeni.png" target=_blank><BR><BR>KENILWORTH<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statekirs.png" target=_blank><BR><BR>KIRSTENHOF<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statekomm.png" target=_blank><BR><BR>KOMMETJIE<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statelake.png" target=_blank><BR><BR>LAKESIDE<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statemari.png" target=_blank><BR><BR>MARINA DA GAMA<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statemuiz.png" target=_blank><BR><BR>MUIZENBERG<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statenoor.png" target=_blank><BR><BR>NOORDHOEK<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/stateobse.png" target=_blank><BR><BR>OBSERVATORY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/stateotte.png" target=_blank><BR><BR>OTTERY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/stateprin.png" target=_blank><BR><BR>PRINCESSVLEI<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statestra.png" target=_blank><BR><BR>STRAWBERRY LANE<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statesunv.png" target=_blank><BR><BR>SUNVALLEY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/statetoka.png" target=_blank><BR><BR>TOKAI<BR></A></SPAN> <BR><BR><A class=anchors href="#whynot3">WHERE IS YOUR GROUP?</A> <BR> <p>Overall state:</p> <P><IMG align=top src="sarah/stateover.png" height=370></P> <p>! 14% of toads encountered were dead !</p> <br> <br> <br><p><strong>Sexes</strong></p> <p>When rescuing toads volunteers collect demographic statistics. This is simply are the toads: Male, Female (in eggs {plump, on the way to breed}, without eggs {finished breeding or not breeding, often thin}, breeding state unknown), Sex unknown, Juveniles (less than 75 mm long) and Toadlets (less than 15 mm long). Toadlets are not usually seen during the breeding season, and Juveniles do not normally migrate to the breeding ponds, but are sometimes encountered. It is important to note if the Females are full of eggs and going to the ponds to breed, or if they are thin and finished breeding. As a rule Females migrate en mass to the ponds, but then sneak back home afterwards, so that most Females rescued are in egg. The categories Unknown are difficult to tell cases, beginner volunteers still finding their feet, and heavy workloads where numbers overwhelmed the volunteers. Sex statistics collected by the different volunteer groups can be found here.</p> <p>Choose a group to look at the sex ratios over time for an area:</p> <SPAN class=titles><A class=titles href="sarah/sexberg.png" target=_blank><BR><BR>BERGVLIET <BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexclov.png" target=_blank><BR><BR>CLOVELLY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexcycl.png" target=_blank><BR><BR>CYCLE TRACK<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexdieo.png" target=_blank><BR><BR>DIE OOG<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexfish.png" target=_blank><BR><BR>FISH HOEK<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexglen.png" target=_blank><BR><BR>GLENCAIRN<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexhout.png" target=_blank><BR><BR>HOUT BAY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexkeni.png" target=_blank><BR><BR>KENILWORTH<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexkirs.png" target=_blank><BR><BR>KIRSTENHOF<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexkomm.png" target=_blank><BR><BR>KOMMETJIE<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexlake.png" target=_blank><BR><BR>LAKESIDE<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexmari.png" target=_blank><BR><BR>MARINA DA GAMA<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexmuiz.png" target=_blank><BR><BR>MUIZENBERG<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexnoor.png" target=_blank><BR><BR>NOORDHOEK<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexobse.png" target=_blank><BR><BR>OBSERVATORY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexotte.png" target=_blank><BR><BR>OTTERY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexprin.png" target=_blank><BR><BR>PRINCESSVLEI<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexstra.png" target=_blank><BR><BR>STRAWBERRY LANE<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sexsunv.png" target=_blank><BR><BR>SUNVALLEY<BR></A></SPAN> <SPAN class=titles><A class=titles href="sarah/sextoka.png" target=_blank><BR><BR>TOKAI<BR></A></SPAN> <BR><BR><A class=anchors href="#whynot3">WHERE IS YOUR GROUP?</A> <BR> <p>Overall sex:</p> <P><IMG align=top src="sarah/sexover.png" height=370></P> <p>Too early to see any trends, but males are prominent as expected at the start of the season!</p> <BR> <A id=top3 name=monitoring2></A> <br> <p><b>Monitoring</b></p> <p>Monitoring involves visiting the ponds and recording breeding activity.
