Objet # : SCP-307

Classe : Keter

Procédures de Confinement Spéciales : SCP-307 doit être maintenu dans une jardinière de 0,5 mètres en acier inoxydable, dans une chambre de culture hydroponique équipée de lumières et de systèmes d'arrosage contrôlable à distance. Les côtés de la jardinière doivent être équipés de lames circulaires rétractables, dont les contrôles doivent être situés en dehors de la chambre de confinement et être contrôlés 24 heures sur 24 en toutes circonstances. La chambre hydroponique doit être contenue dans une salle de 5 m x 5m x 3 m avec des murs, sols et plafond en acier inoxydable. Il ne doit pas avoir de fenêtres dans la salle - toute la lumière doit provenir de l'éclairage, et les observations de SCP-307 doivent être faites depuis une caméra de sécurité. La température de la salle doit être maintenue à 15°C afin d’empêcher la production de graine.

Si il est nécessaire d'entrer dans la salle de SCP-307, cela doit être fait par des robots contrôlés a distance. Absolument aucun être humain ne doit entrer dans la cellule de confinement de SCP-306 depuis l'Incident 307 (voir Addendum 2).

Si des spécimens de SCP-307 sont découverts en dehors de la cellule de confinement, ils doivent être incinérés jusqu'à ce qu'il ne reste que des cendres. Tout membre du personnel ayant touché SCP-307 doit aussi être incinéré.

Description : SCP-307 est une plante grimpante, similaire en apparence au lierre grimpant commun (Hedera helix), à l'exception de la présence d'épines sur la tige et des feuilles ayant tendance à être de teinte violette. La vigne s'enracine à peu près tout les 30,5 cm. approximately every 30.5 cm (12 in). The roots can penetrate any porous material, but not metal. Any part of the plant not connected to a root system is to be considered dead and safe to examine up close.

SCP-307 appears to be carnivorous, and seems to exhibit some degree of intelligence (see Document 307-A). When in the presence of a warm-blooded animal (hereafter referred to as "the victim"), it grows at a startlingly rapid rate in the direction of the animal, often growing three vines at a time in what appears to be a flanking maneuver. Upon contact, SCP-307 appears to paralyze the victim, and then liquefy and drain all internal organs, musculature, and blood. The mechanisms by which it does this are presently unknown; they have, however, led to researchers calling it "spider ivy".

SCP-307 was first discovered by Agent "Apocalemur" in ████████, ████, where he witnessed it rapidly growing up the trunk of a tree and consuming a nest of American robins. Further examination has revealed the prevalence of the plant throughout North America. It has shown itself to be highly resistant to any attempts at poisoning. This has included all commercially available herbicides, exposure to allelopathic plants, and formaldehyde. Except for the sample obtained for study, the plant has been burned wherever it has been encountered - however, it is very likely that numerous specimens still exist outside of Foundation control. SCP-307 is only kept alive in the hopes of engineering a biological agent to use on the wild population.

Document #307-A: Experiment logs

Experiment 1: █/██/████. Tray of mealworms introduced to cell.

Result: SCP showed no signs of movement.

Experiment 2: █/██/████. Chilean rose-hair tarantula introduced.

Result: SCP showed no signs of movement. Did not respond when tarantula climbed onto SCP.

Experiment 3: █/██/████. Live mouse introduced to cell.

Result: SCP immediately began to grow in the direction of the mouse. One vine extended directly towards it, while two more grew around and in front of it, effectively surrounding the mouse. Mouse immediately became rigid and stopped moving upon contact with SCP-307. Behavior continued for 26 seconds before mouse fell on its side, obviously dead. Vines outside the planter were severed, allowing D-class personnel to collect mouse. Upon retrieval, mouse was noted to appear to be lacking any anatomic structure beside skin and bones. Mouse was taken for further examination.

When mouse was dissected, researchers noted a complete absence of blood, internal organs, and musculature. All interior structures were instead replaced with a system of roots, which researchers traced back to the mouse's skull. A single seed was found inside the mouse's otherwise empty brain cavity. Mouse was subsequently burned.

Experiment 4: █/██/████. Jar containing 130 aphids introduced. Additional camera added for closeup viewing.

Result: Aphids proceeded to attach themselves to SCP-307 and feed. SCP-307 did not respond in any visible manner. All aphids were dead within five (5) minutes of first feeding. Potential for use as insecticide noted.

Addendum 1: Notes of interest taken by Agent Apocalemur during observation of SCP-307

…The energy necessary to facilitate such a rapid growth rate would be astronomical, yet SCP-307 seems able to "pursue" prey regardless of available light or time since it last fed…

…The behavior exhibited by SCP-307 during Incident 307 would suggest the presence of some kind of botanical muscle. Examination of severed vines has revealed no structure that could conceivably serve this purpose…

Addendum 2: In light of Incident 307, SCP-307 has been upgraded to Keter class. Appropriate adjustments to containment protocol have been made. See Incident Report 307 for more details.
