Upon our arrival, we soon completed passport control and baggage reclaim and made our way out to the arrivals area, before making our way to the bus stop for the bus to the car-rental area to collect the minibus. Soon the luggage was stowed, and we boarded the vehicle for the journey to the Vercors region. Serin and Skylark were recorded in the Hertz car park. We drove south-westwards on the A43 and A48 Motorways, stopping for a short comfort break at Aire L’Isle d’Abeau service area, before continuing south towards Grenoble. Along the way, we recorded Rook, Kestrel, Barn Swallow and Green Woodpecker. At Grenoble we left the motorway, continuing through Sassenage, where we turned up onto the Vercors Plateau. Along the way a Song Thrush was seen, as well as Ononis viscosa (Sticky Restharrow) and Saponaria officinalis (Soapwort). It was not long before we arrived in Lans en Vercors and the Hotel Le Val Fleuri, our base for the rest of the tour. Here we were met by our host, Eliane Bonnard. After freshening up, we reassembled for dinner and Paul outlined the early part of the week ahead for us. Day 2 Thursday 13th July Les Merciers – Les Bruyères An early wander by the birders produced Swift, singing Blackcap and Carrion Crow. Following a splendid breakfast, we made the short journey to the small hamlet of Les Merciers. Here we explored a steep path, rocky lane-sides and some meadows. It was a bright, sunny morning, and insects were active. Leaving the minibus, we began to explore. Coal Tit and Common Chaffinch were heard, and Large Wall Brown, Damon Blue, Scotch Argus, Blue-spot Hairstreak, Poplar Admiral and Purple Emperor butterflies were seen. Moving on up the steep path, we began to find some plants, including Epipactis atrorubens (Dark Red Helleborine), Dianthus sylvestris (Wood Pink), Anacamptis pyramidalis (Pyramidal Orchid), Gymnocarpium robertianum (Limestone Fern), Verbascum nigrum (Dark Mullein) and Buphthalmum salicifolium (Yellow Ox-eye). We now moved along a rocky lane bank, adding Sedum dasyphyllum (Fat-leaved Stonecrop), Sedum forsterianum (Rock Stonecrop) and Rhamnus alpinus (Alpine Buckthorn). Additional butterfly species included Pearly Heath, Small Heath and Baton Blue. In some rocky meadows we found Dianthus carthusianorum (Carthusian Pink), Thalictrum minus (Lesser Meadow-rue) and Gentiana cruciata (Cross Gentian). Here, Black Kite, Yellowhammer, Crag Martin, Alpine Swift and Kestrel were added, together with Spotted Fritillary, Provence Chalk-hill Blue, Dark Green Frillary and Dusky Meadow Brown butterflies We now returned to the vehicle, and made our way up towards Autrans, in order to find a picnic site. This was situated a little way along a forest route, in a large, grassy clearing. During the meal, Large White and Arran Brown butterflies were seen and Bullfinch was heard. © Naturetrek December 17 1 Vercors in Summer Tour Report After eating, we made our way to the wet meadows at Les Bruyères, hoping to try and find Marsh Warbler. A small pond had a good stand of Typha angustifolia (Lesser Bullrush) and substantial population of the hybrid Edible Frog. Other plants included Vicia cracca (Tufted Vetch), Trifolium hybridum (Alsike) and Mentha longifolia (Horse Mint). Birds seen were Whinchat, Carrion Crow and Black Kite. The Marsh Warbler was heard but would not show itself. We did, however, see Common Goldenring, Common Darter and Broad-bodied Chaser dragonflies and Small Skipper, Dingy Skipper and Reverdin’s Blue butterflies. We now made our way back to Lans en Vercors. Day 3 Friday 14th July Bois de Mures - Les Jarrards – Gorges de la Bourne – Font d’Urle – Col de Rousset This morning, Green Woodpecker, Robin and Serin were all recorded in the garden of the hotel. After breakfast we headed north to the Bois des Mures, to look for Epipogium aphyllum (Ghost Orchid). Luckily, our timing was good, and we found several emerging spikes of this rare species. In addition, we also found Monotropa hypopitys (Yellow Bird’s-nest) and Epipactis muelleri (Mueller’s Helleborine). A roadside bank produced Digitalis lutea (Small Yellow Foxglove), Gymnadenia conopsea (Fragrant Orchid), Luzula nivea (Snowy Woodrush) and Melampyrum nemorosum (a Cow-wheat), as well as the fruiting spikes of Traunsteinera globosa (Round-headed Orchid). We now made our way south, passing through Les Geymonds and down to La Chappelle en Vercors, where we turned off toward Vassieux and made our way up over the Col de la Chau (1,337 metres), and on to the Font d’Urle. We paused briefly at the cemetery near Vassieux, where the victims of a Nazi reprisal against the Resistance, in 1944, are buried. A brief pause to over-look the valley produced Marbled White, Pearly Heath, Blue-spot Hairstreak and Apollo butterflies. A little further on, we stopped for our picnic in the forest. While Paul set up lunch, we expored the adjacent woodland clearings and verges, finding Platanthera bifolia (Lesser Butterfly Orchid), Geranium sylvaticum (Wood Crane’s-bill), Campanula rhomboidalis and Paris quadrifolia (Herb- Paris). The curious Bee Beetle was also found. Upon our arrival on the Font d’Urle, we parked by the refuge and set off to explore, accompanied by a small flock of Alpine Choughs which were patrolling the slopes. The Font d’Urle (1,500 metres) is a winter ski station with limestone outcrops and meadows. Early finds were Dianthus monspessulanus (Fringed Pink), Onobrychis arenaria (a Sainfoin), Alchemilla conjuncta and Gypsophila repens (Alpine Gypsophila). Black Redstart, Water Pipit, Common Linnet and Common House Martin were noted, as well as a Mountain Hare. Additional plants found were Veronica spicata (Spiked Speedwell), Gymnadenia austriaca var. gallica (a dark Vanilla Orchid), Persicaria bistorta (Bistort) and Hypericum richeri subsp. burseri (Alpine St. John’s-wort), as well as Common Brassy Ringlet, Niobe Fritillary and Purple Treble-bar moth. We now made our way back over the Col de la Chau and on through Vassieux, towards the spectacular Col de Rousset, where we made a short stop to admire the view. Here, we found Centranthus angustifolius (Narrow-leaved Red Valerian) and Galeopsis angustifolius (Red Hemp-nettle), as well as Apollo, Painted Lady and Large Wall Brown butterflies. 2 © Naturetrek December 17 Vercors in Summer Tour Report Moving back through the tunnel, we drove towards St. Agnan, and on to the small town of La Chapelle en Vercors, where we took dinner at the Hotel Bellier, before returning to our hotel in Lans en Vercors. Day 4 Saturday 15th July Presles – Forêt Domaniale des Coulmes – Pont en Royans Following another excellent breakfast, we left the hotel and drove south once again through the Grand Goulets Tunnel, down to Ste. Eulalie en Royans and up through Pont en Royans, to where we turned west and began to climb up towards the Route de Presles. This is a magnificent limestone cliff formation, overlooking the Commune de Châtelus and the valley of the River Bourne. We made our first stop about three-quarters of the way up, where we explored the banks and meadows beside a quiet lane. Here we found Gatekeeper, Large Blue, Swallowtail and Great Banded Grayling, and Lulworth Skipper butterflies. Plants included Prunella grandiflora (Large-flowered Self-heal), Catanache caerulea (Blue Catanache), Quercus pubescens (Downy Oak), Epipactis mulleri (Muller’s Helleborine) and Anthericum ramosum (Branched St. Bernard’s Lily). Common Wall Lizard was also seen, in the morning sunshine. We now moved on up to the higher cliffs of the Route de Presles, and on into the Forêt Domaniale des Coulmes to a picnic site at the Fontaine de Petouze. During the lunch stop, Marbled Fritillary, Scarce Copper, Heath Fritillary and Swallowtail butterflies were seen. For the plants, Saxifraga rotundifolia (Round-leaved Saxifrage), Lilium martagon (Martagon Lily) and Sambucus ebulus (Dwarf Elder) were also recorded. We now made our way back down through Presles and the splendid cliffs of the Route de Presles, and on towards Pont en Royans, parking on the outskirts of the town. The river-gorge bank had Buddleja vegetation, on which we found Cleopatra, Scarce Swallowtail, Southern White Admiral and Small White butterflies, and the gorge had White-throated Dipper and Grey Wagtail. Visiting the Restauant Picard, we sampled their wonderful selection ice creams. Crag Martins were very active, and the marginal vegetation of the river gorge was a magnet for insects. It was then time to make our way back to Lans en Vercors for dinner, after which Paul set a moth trap. Day 5 Sunday 16th July Route Forestière de la Molière. After breakfast, we made the short journey to the Route Forestière de la Molière, part of the Forêt Commune d’Autrans. The area comprises mixed woodland, open rides, rocky banks and open meadows. From Lans en Vercors, we took the road up towards the towns of Meaudre and Autrans, turning right onto the forest road. We made our way up towards the Refuge des Feneys, where we turned right and up to the car park at the start of the circular walk we were to undertake, the Route de la Molière. Our route would take us through woodland and open pasture, and we began working our way through some sub-alpine woodland.
