Yellow Birds Nest 23012


Family 

Ericaceae


Species Description

Yellow bird’s Nest Monotropa hypopitys AKA Ductchmans Pipe is a short, perennial plant, growing to 30cm..
The whole plant is a waxy, pale brownish-yellow.
Flowers are tubular with 4 to 5 sepals united at the base
 The 4/5 petals are dull yellow, 8-12 mm long on a drooping stem that becomes erect in fruit.
Leaves are scale-like and close to the stems.
Plants are fleshy and grow 10–35 cm tall.

True stems are nonexistent. Instead, the only part which emerges from the soil are unbranched adventitious inflorescenceswhich are developmentally similar to adventitious roots.[2] All parts of the plant are pale yellowish white to reddish-tinged. The bracts are 5–10 mm long scale-like structures, which cover most of the inflorescence. Plants flower from April to December depending on the geographic region (June to September in North America). The flowers are pendulous when young, but become erect when they begin to mature into the fruit which is a capsule. The flowers are 9–12 mm long and produced in a cluster of 1–11 together at the apex of the inflorescence, which is a raceme. It flowers between early summer and mid autumn; plants that flower in summer are yellow and sparsely hairy, while those that flower in autumn are red and densely hairy. These two color "forms" overlap in flowering time. It has been suggested that yellow individuals are largely self-pollinating.[3]

It is considered to have two subspecies (Stace 1997), but morphology is not always reliableand a need to check chromosome number to be absolute

ssp. hypophegea (Wallr.) Holmboe which is glabrous and has a chromosome number 2n = 16 (Stace 2010).
ssp. hypopitys,    which has pubescent stamens, carpels and petals; 2n = 48 (Stace 2010).

Biology

This plant does not contain chlorophyll; it is a myco-heterotroph, getting its food through parasitism upon fungi rather than photosynthesis. Monotropa contains no chlorophyll, and was until recently thought to be saprophytic (deriving nutrients from decaying leaf litter) but recent research shows that it is actually epiparasitic, using Tricholoma fungi to extract nutrients from living trees in its vicinity (Leake et al. 2004). These fungi form a mycorrhiza with nearby tree species.has popularly been described as a saprophyte, howe
ver it is more appropriate to classify yellow bird’s nest as a myco-heterotroph meaning it gains energy from mycorrhizal fungi (Leake 2005). M. hypopitys roots are sheathed in ectomycorrhizal fungal mycelium, and nourished exclusively by carbon passing through a common mycorrhizal network linked to adjacent autotrophic trees, deciduous or coniferous It is usually found in woods or in scrub.

Status

Origin: native. It was first recorded by Robert Plot at Stokenchurch in 1677 (Clarke 1900), although he mentions earlier records by John Goodyer (1592-1664), which must pre-date this.

Nationally Scarce species in Britain,   Recorded  in 103 hectads in the New Atlas (Preston et al. 2002). 

Threat: its status in the JNCC Red List (Cheffings & Farrell 2005) is ‘endangered’ - an assessment based on the Change Index, which shows it to be declining in Britain. Rumsey, in the New Atlas, also describes it as having suffered a prolonged decline.

Conservation: It is  listed it as an ++ axiophyte, but it is not quite obvious which BAP habitats it occurs in. It is debatable whether it really warrants such a status, and more research is needed.

++ Lists of axiophytes for various BAP habitats can be used as an empirical measure for sites of nature conservation interest. This allows landowners and others to see how decisions have been made.

Descriptive Botany 

Pyrola rotundifolia is an evergreen scented  A rhizomatous, mycorrhizal Perennial growing to 0.3 m (1ft) by 0.3 m (1ft in). It is hardy to zone (UK) 4. It is in leaf 12-Jan It is in flower from Jun to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, flies, self. The plant is self-fertile.and therefore can survive a s discrete colonies giving the right habitat or lack of Harmful intervention
  • The flower stem (scape) is pale, up to 40cm, with 1 or 2 brown scales.
  • Flowers are 5-merous, approximately 1cm across, with pure white petals.
  • Anthers (10) are orange and the style is 7-8mm long, and curved with a 5-lobed, capitate stigma.
  • The 5 ovaries form a fleshy ring round the base of the style.The fruit is a capsule.
  • Leaves are at the base of the stem (radical), round to oval, and up to 5cm long

Management Points

Round leaved wintergreen  should occur in seasonally flooded areas. Areas and should be left  uncleared because this rare plant favours shade  associated with willow which is dominant in this area. .This is a particularly relevant point given the unusual PVA substrate which has a high permeability , prone to drying out ,coupled with  the lack of soil means this particular ground ecology is poorly understood.The nature of this associated habitat with Yellow Birds Nest Monotropa hypopitys with its unique fungal symbiosis and ground ecology also means that the leaf litter layer should be left undisturbed and natural cycles left unalterred given the longitudinal age of both colonies. The limiting nature of this man made sub surface likely limits realistically tree species to those with shallow root systems It goes without saying such areas should have controlled and limited access (See Original Management plan)and that  clearing of leaf litter should not be applied. Occasional bramble clearance although peripheral retention would contribute to site restriction

Site Appraisal

Whilst most ecologists will spout conventional practice an appraisal an  understanding of this site and its sub-soil is vitally important . The siting of Willow Carr is at or just below the water level and results in seasonal water retention or flooding for this slow growing plant . The nature of the soil or lack of it on the surface of the predominant PVA Pulverised Fly Ash deposited as a historical  waste legacy has a High Permeability . Removing the Tree Canopy would cause much of the soil sub-surface to loose moisture or and would not promote the high Humidity levels associated with this hollow and Tree /  Shrub layers generaly needed by the plant . Additionally there is also a complex Mycorrihzzial fungal relationship with other rare plants specifically relating to Grey Willows 

Monitorring

Like all good practice intervention strategies and outcomes should be dictated by good Monitorring . This should include Year on Year  Quadrat Data on flower stands numbers and distribution and also annual records of accumulated leaf litter . FEET have limitted but nevertheless supportive evidential data to support the suggested management intervention

Trends 

This subspecies has undergone a marked decline since 1930, despite some local increases in disused quarries. Reasons for the losses include afforestation and rubbish tipping, but the most serious declines, such as its near extinction in East Anglia, result from changes in fen management.
