Cathedral groves of large conifer trees and lush undergrowth are characteristic of the best groves of Čorkova Uvala. The largest tree next to the person is a fir of ~440cm in girth; the other trees are spruce and beech. Elevation is ~950m

Dense collections of towering trees occupy the gentler sites of the reserve where terrain is less rugged. Some of the spruce and fir in this stand reach 50m in height. Abundant fir regeneration can be seen around the large spruce in the foreground. Elevation is ~850m

Old spruce trees often form imposing groves in Čorkova Uvala. Despite literature recording fir as the largest species of the reserve, the largest trees personally measured for this report were spruce. Elevation is ~850m

Cathedral grove dominated by large spruce trees and a few firs. Dense undergrowth of ferns. Elevation is ~960m

Shady grove with large fir and spruce trees, also a few beech trees. For scale, the man in the photo is about 193cm tall. Elevation ~950m

Large fir growing on the stony edge of a sinkhole, with a girth of ~440cm and height of ~40m despite a heavily damaged top. Undergrowth of the left foreground is hart's-tongue fern (Asplenium scolopendrium), which is abundant in Čorkova Uvala. It is interesting to note that this fern appears to be very rare in coastal beech, fir, and spruce virgin forests of Croatia. Elevation is ~900m

Two large spruce trees growing on a small ridge between two sinkholes. This type of topography is typical for Čorkova Uvala. The larger of the two is seen to the left with a notable corkscrew shaped lightning scar running down its wavy trunk. It is the widest tree recorded for this report. Elevation is 830m

Dense undergrowth below a grove of beech trees. The large tree shown right is the tallest beech measured with a height of 44m. Elevation is ~900 m

Large trees from left to right are fir, spruce, and beech. Elevation ~960m

Large firs of nearly 50m tall growing on gentle slopes at the edge of a small valley at ~850m

Dense stand of large conifers with abundant fir and spruce regeneration at ~850m

Steep stony slopes give way to lush undergrowth at the bottom of sinkholes. This stark contrast and variation between growing sites is a relatively common feature of karst bedrock, however the phenomenon is especially well developed in Čorkova Uvala. Elevation is ~850m

Large spruce tree, deadwood, and fir regeneration. Elevation is ~970m

Large mossy fir tree in the center, also the bark of spruce tree to the left. Elevation ~950m

Small windthrow with fallen trunks on the edge of a sinkhole. Cliff outcrops like the one on the right are especially common on ridgetops or hills. Elevation is ~900m

Young beech trees and the decaying snags of large fir trees. Each of the snags can be seen in a progressively greater state of decomposition from left to right. Elevation is ~900m

Large examples of hart's-tongue ferns. Also a sycamore maple in the center of the photo. Elevation is ~900m

Largest recorded spruce of Čorkova Uvala. Girth is ~500cm and volume is estimated at up to 30 cubic meters. Height is only 43m as lightning appears to have damaged the top. Elevation is 830m

The largest spruce tree measured, as well as the largest tree measured in this part of Čorkova Uvala. It has a cbh of about 470cm and an estimated volume over 30 cubic meters. Elevation is ~970m

The tallest measured spruce (53 m)

Čorkova Uvala valley and meadow. This meadow was the site of the former village of Čorkova Uvala from which the old growth reserve got its name. The old growth forest is in the near vicinity of this meadow. The highest peak visible to the far left is named Cigelj, and it is also the second highest peak in Plitvice National Park at 1252m

Čorkova Uvala meadow at 830 m in July. Cigelj peak rises above the valley
