<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:black" lang="EN-US">Some of the herbaria are in build-in cabinets, and therefore need new housing, but since we do not know exactly how the new collection facilities
will end up, we are NOT interested in purchasing new cabinets at this moment.<u></u><u></u></span></p>
<p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:black" lang="EN-US">The aim is to keep all the collections accessible at all times in the coming years (except when doing the actual move

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:black" lang="EN-US">The temporary storage is actually quite nice and our staff will be working there permanently. We will be able to control the relative humidity, but
we do not have a chance of securing the facility in regard to pests.<u></u><u></u></span></p>

</span></span></span><u></u><span style="font-size:10.0pt;font-family:"Verdana","sans-serif";color:black" lang="EN-US">To pack and seal the material from the different shelves individually in plastic, maybe with a light vacuum in order to minimize the mechanical
tear.<u></u><u></u></span></p>
<p><u></u><span style="font-size:10.0pt;font-family:Symbol;color:black" lang="EN-US"><span>·<span style="font:7.0pt "Times New Roman"">

of placement of individual pallets together with the meta-registration of individual boxes, should enable us to find the desired material at any time.<u></u><u></u></span></p>

five years’ time.<br>
